This book was released on 2022-02-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the first successful realization of a compact, low-noise, and few-cycle light source in the mid-infrared wavelength region. By developing the technology of pumping femtosecond chromium-doped II-VI laser oscillators directly with the emission of broad-stripe single-emitter laser diodes, coherent light was generated with exceptionally low amplitude noise — crucial for numerous applications including spectroscopy at high sensitivities. Other key parameters of the oscillator's output, such as pulse duration and output power, matched and even surpassed previous state-of-the-art systems. As a demonstration of its unique capabilities, the oscillator's powerful output was used to drive — without further amplification — the nonlinear generation of coherent mid-infrared light spanning multiple octaves. The resulting table-top system uniquely combines high brilliance and ultrabroad spectral bandwidth in the important mid-infrared spectral range. The rapid development of this technology is comprehensively and lucidly documented in this PhD thesis. Together with a thorough review of literature and applications, and an extensive analysis of the theoretical foundations behind ultrafast laser oscillators, the thesis will serve as a valuable reference for the construction of a new generation of mid-infrared light sources.

Book excerpt: The synchronously pumped optical parametric oscillator is an efficient, wavelength tunable laser source that makes it possible to generate wavelength tunable picosecond and femtosecond pulses which cover the wavelength range from visible to midinfrared. A theoretical model for calculating the effective gain of parametric generation and amplification of ultrashort optical pulses is presented. An analytical formulation for the parametric efficiency coefficient and the effective gain in terms of six spatial and temporal characteristic lengths is obtained. Also presented is the experimental work to construct such a source based on the additive pulse mode locked Nd:YLF laser pulses. The design and characteristics of the KTP based picocsecond synchronously pumped optical parametric oscillator are discussed and compared with the previous theoretical work. Efforts to extend the wavelength range to 10 microns by use of a newly developed crystal are included. Parametric generation of femtosecond optical pulses is also presented.

This book was released on 2017-02-27 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is interesting to analyze the application of mid-infrared (MIR, 1000-5000 nm) radiation to study the dynamics of the nonlinear optical response of ablated molecular structures compared with commonly used Ti: sapphire lasers for plasma high-order harmonic generation (HHG), including the studies of extended harmonics at a comparable conversion efficiency with shorter wavelength laser sources, and a search for new opportunities in improvement of the HHG conversion efficiency in the mid-IR range, such as the application of clustered molecules. This book shows the most recent findings of various new schemes of the application of MIR pulses for HHG in laser-produced low-ionised, low-density plasma plumes, which could be dubbed for simplicity as 'plasma harmonics'. The use of any element of the periodic table, as well as thousands of complex samples that exist as solids largely extends the range of materials employed, whereas only a few rare gases are typically available for gas HHG. The exploration of practically any solid-state material through the nonlinear spectroscopy comprising laser ablation and harmonic generation can be considered as a new tool for materials science. Thus the MIR pump based laser-ablation-induced high-order harmonic generation spectroscopy can be considered a new method for the study of materials and one of most important applications of plasma HHG.

Available in PDF, EPUB and Kindle. Book excerpt: A study of heterodyne generation of very-far-infrared radiation (10-400/cm) from two visible or near-infrared laser beams has been performed. Two possible nonlinear mechanisms that can provide mixing were studied both theoretically and experimentally, with emphasis on the latter. In one, the electric field of the incident radiation modulates the susceptibility or index-of-refraction: in the other, the absorption coefficient. The latter was calculated to be the more promising mechanism, with possible generation of 10 to the -8th power W of radiation at 20/cm; the former would, at best, produce 10 to the -12th power W of radiation. The two laser beams were derived from a single GaAs injection laser which is sufficiently tuneable so that the difference frequency could be tuned to the required 50-100/cm. The mixing material was semi-insulating GaAs in a large dc electric field for the nonlinear absorption, semi-insulating GaAs or GaP, LiNbO3, for nonlinear susceptibility. The far-infrared radiation was collected and detected with cooled bolometers optimized to a sensitivity of a few times 10 to the -13th power W. No clearcut difference-frequency radiation was detected by either technique. In some cases radiation up to 5 x 10 to the -12th power W was clearly present, but it did not have all the required characteristics, although it could not be ascribed to any other source either. In any case, it was concluded that it is not feasible at this time to obtain a practical amount of far-infrared radiation by heterodyne techniques. Rather, a considerable improvement in the output of tuneable lasers must be awaited. (Author).

This book was released on 2015-10-14 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines laser generation from the ultraviolet to the short edge of the mid-infrared band by exploiting the nonlinear effects in photonic crystal fibers (PCFs). Several different physical mechanisms are investigated by using homemade PCFs with elaborately customized dispersion profiles. A particular focus is on the development of fiber optical parametric amplifiers (FOPAs) and oscillators (FOPOs) based on the PCFs with a zero-dispersion wavelength of ca.1.06 μm. In particular, several schemes are proposed for solving the key problems involved in the application of FOPOs. These oscillators can be made more convenient to use by optimizing the wavelength-tuning mechanisms and made more energy-efficient with the help of specially designed cavity structures. Today’s oscillators are more reliable, powerful and maneuverable than ever. This thesis provides a systematic road map in connection with the study of nonlinear wavelength generation in PCFs, from their fiber design and technical fabrication, to their physical mechanism and experimental investigation.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this thesis has been the development of a new class of advanced solid-state photonic sources for the mid-infrared (mid-IR) spectral regions, where there exists a severe shortage of practical coherent laser sources, and many scientific and technological applications can benefit. The strategy has been to exploit nonlinear optical techniques based on difference frequency generation (DFG), parametric generation and oscillation, in the latest class of mid-IR nonlinear materials, in combination with the most advanced lasers pump sources based on fiber laser technology, to realize novel, high-power coherent source with broad tunability in the mid-IR. Accordingly, we demonstrate an angle-tuned MgO:PPLN picosecond OPO, synchronously pumped by a Yb-fiber laser, for the first time to the best of our knowledge. The OPO is tunable from 1413-1900 nm in the signal togerther with idler tunability across 2418-4307 nm providing a total tunability of 2376 nm in the near-to-mid-IR region, simply by angular interrogation of the MgO:PPLN crystal at room temperature. Using a 10% output coupler, we were able to extract up to 2.4 W of signal at 1664 nm together with an idler power of 1.7 W at 2950 nm, corresponding to an overall extraction efficiency of ̃45% with good beam pointing stability of better than 30 μrad and 14 μrad for the signal and idler, respectively. These results indicate the potential for rapid and wide tunability of high-power OPOs as compared to the temperature tuned devices. In addition, we have demonstrated a novel device based on a tandem configuration, for an injection-seeded pulsed OPO system. Using a 38-mm-long PPLN crystal, we have produced ̃0.94 W of average power with 9.7% slope efficiency at 1677 nm, for a pump power of 10 W at 80 kHz repetition rate. The measured optical bandwidth of signal is less than 20 MHz, and the seeding operation is achieved over signal wavelengths ranging from 1510 to 1677 nm, providing a total seeding range of 167 nm in the near-IR region. From a more general viewpoint, the method shownhere will also work at other wavelength range of OPO as well, opening a new path towards injection-seeding or injection-locking of pulse OPOs with full tuning range and high spectral purity. Finally, we present detailed characterization of optical properties of the recently developed nonlinear material, orientation-patterned gallium phosphide (OP-GaP), by performing DFG experiments in the 2492-2782 nm wavelength range in the mid-IR. Detrimental issues such as thermal effects and residual absorption have been studied and confirmed by performing relevant measurements. Temperature and spectral acceptance bandwidths for DFG in the 40-mm-long OP-GaP crystal have been measured to be 18 oC and 4 nm, respectively, at 1766 nm. Further, we have measured the damage threshold of the OP-GaP crystal to be 0.8 J/cm2 at 1064 nm, for the first time. The polarization dependence of the input beams on the DFG power has also been systematically investigated. To our knowledge, this is the first report on tunable DFG in OP-GaP, as well as the first nanosecond DFG source based on this new nonlinear material.
