This book was released on 2020-11-25 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study looks at the basic principles of optical parametric processes and recent results on the rapidly developing optical parametric device technology. The theoretical basis of stimulated and spontaneous optical parametric processes and detailed design considerations of optical parametric oscillators and amplifiers are discussed, followed by a review of the materials properties of the most important nonlinear optical crystals for such applications. It concludes with a review of the recent developments on practical low-repetition rate nanosecond optical parametric oscillators and broadly tunable high-repetition rate continuous-pulse-train femtosecond optical parametric oscillations from the uv to the mid ir.

This book was released on 2017 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A demand for ultrafast, highly energetic laser sources in the infrared exists for various applications such as high-harmonic generation, waveguide inscription, and remote sensing. These applications require high repetition rates for faster processing speed and better signal-to-noise ratios. Until recently, laser pulses used in these systems were usually provided by optical parametric oscillators and amplifiers pumped by Ti:sapphire laser systems. The output power and spectral bandwidth of this pump source are fundamentally restricted due to unavoidable limitations caused by the quantum-defect heating and restricted emission spectrum of the gain medium. Advancements to Yb-based sources have provided a significant increase in average power and pulse energy available from ultrafast pumps, thereby increasing the capabilities of parametric devices. In this thesis, an ultrafast optical parametric oscillator was constructed as a test bed for investigating the scaling potential of these devices. The main goals of this study were to utilize recent technological advancements to ultrafast pump sources and test the limits for obtaining high-energy pulses with high average powers from an optical parametric oscillator. Various nonlinear crystals and parametric pumping geometries were investigated to determine how best to use the available power of a home-built pump laser and the general potential for scalability. To utilize recent developments of similar pump sources, a long cavity was designed to take advantage of the high-average-powers with scalable pulse energies. While the designing the cavity, it became apparent that the cavity length could be done easily without notable change to critical cavity parameters by using telescopic imaging relays. It was discovered that limitations to the power scalability of this system were directly linked to problems with the thermal management of the nonlinear crystal. While minor changes could have been implemented to reduce the impact of these boundaries, understanding thermal effects in parametric devices will be critical to fully utilizing the state-of-the-art pump sources. Simple and cost-effective methods were developed for characterizing the impact of the thermal gradient on the available gain. This analysis could easily be extended to other systems for predicting and mitigating thermally induced power scaling limitations."--Pages xiii-xiv.

Available in PDF, EPUB and Kindle. Book excerpt: This volume considers optical parametric generation and amplification (OPG/OPA), as a means for producing a tunable optical parametric device. It reviews the OPA/OPG systems using various crystals pumped by lasers at various frequencies with pulse duration ranging from picoseconds to femtoseconds. Part two covers the theoretical background for design of an OPA/OPG system, using two newly discovered nonlinear crystals. Experimental design considerations are discussed in section three, including the section of nonlinear crystals, pumping sources and optical configurations. In section four, the experimental results obtained are compared with the theoretical calculations.

This book was released on 2014 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we have demonstrated various ultrafast optical parametric oscillators (OPOs) based on different nonlinear media. The thesis consists of OPO systems, novel techniques, designs, and concepts that has facilitated the wavelength accessibility from 1 μm in the near-infrared region to as far as 8 μm in the mid-infrared region. We developed a fs OPO based on BiB3O6 (BIBO) directly pumped the Kerr-lens mode-locked (KLM) Ti:sapphire laser. This system could provide broad and rapid tuning from 1420-1560 nm just by changing the cavity length. Also, by exploiting the unique optical properties of BIBO under type I (e¿oo) interaction, we have demonstrated the first self-phase-locked degenerate fs OPO. Further, we have developed a technique called synchronous retro-reflection for threshold reduction and signal amplification before the onset of the oscillation. This technique is generic and is particularly useful while deploying ultrafast OPOs with birefringent materials that have relatively low nonlinear gain and when we have limited pump power. In addition, we have developed a dual-wavelength fs OPO with arbitrary and independent tuning by making use of anti-resonant-ring (ARR) or Sagnac interferometer. This universal technique of coupling two optical oscillators can be employed in any time regime (cw to ultrafast pico or fs) irrespective of the operating wavelengths. This conceptual technique can be used for intracavity terahertz (THz) generation which exploits the high intensity intracavity oscillating pulses. Also, we have developed a dual-crystal, double-pumped OPOs for intracavity signal amplification in fs regime as well as in ps regime, for arbitrary and independent wavelength tuning. In both systems two crystals share the same optical cavity but are pumped independently by a single laser source. Finally, we have devised and experimentally demonstrated a novel concept of pumping an OPO within another OPO using a composite cascaded cavity design. This all solid-state Ti:sapphire-pumped fs OPO system is potentially capable of providing access to mid-infrared region beyond 4 μm to as far as 18 μm by careful selection of the nonlinear medium.
