This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of continuous wave singly resonant optical parametric oscillators (CW SROs) has been limited in the past mainly because of the high threshold powers necessary. Thresholds of SROs are orders of magnitude greater than doubly resonant oscillators. While lithium niobate has long been in use as a nonlinear material, periodically poled lithium niobate (PPLN) recently emerged as an excellent source for CW SROs. Quasi-phase matching with PPLN has allowed access to the higher nonlinear coefficients of lithium niobate permitting construction of CW SROs. By placing the OPO within the laser resonator, threshold should be significantly reduced. We have designed, built, and investigated an optical parametric oscillator within a laser cavity to access the high circulating fields within the resonator. The intracavity OPO acted as the output coupler for the laser and ideally the total down converted power from the OPO should approach the maximum output power available from th pump laser under optimal output coupling. PPLN OPOs were built within the resonators of a lamp-pumped Nd:YAG laser and a diode-pumped Nd:YVO4 laser. Combined idler output at 3.3 microns from both ends of an intracavity 30-mm PPLN OPO was 1.15 W. Output of the Nd:YVO4 laser optimized for 1.064-micron output with the same resonator was 5 W. The entire device, except for power supply and cooler, fit on a 1' x 2' breadboard.

This book was released on 2011 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous-wave (cw) optical parametric oscillators (OPOs) are working horses for spectroscopy for near and mid infrared wavelengths. However, in the terahertz frequency range (0.1 to 10 THz), the pump threshold for oscillation is larger than 100 W due to high absorptions and thus exceeds the power of standard cw single-frequency pump sources. In this thesis, the first cw OPO capable of generating terahertz radiation is demonstrated. To overcome thethreshold, the signal wave of a primary infrared process is resonantly enhanced to serve as a pump wave for a cascaded parametric process with one wave being at the terahertz frequency level. Such a device inhibits high potential for applications in areas like astronomy, telecommunications or high-resolution spectroscopy.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: We present a continuous-wave singly-resonant optical parametric oscillator with 1.5% output coupling of the resonant signal wave, based on an angle-polished MgO-doped periodically poled lithium niobate (MgO:PPLN), pumped by a commercial Nd:YVO4 laser at 1064 nm. The output-coupled optical parametric oscillator delivers a maximum total output power of 4.19 W with 42.8% extraction efficiency, across a tuning range of 1717 nm in the near- and mid-infrared region. This indicates improvements of 1.87 W in output power, 19.1% in extraction efficiency and 213 nm in tuning range extension in comparison with the optical parametric oscillator with no output coupling, while at the expense of increasing the oscillation threshold by a factor of ∼ 2. Moreover, it is confirmed that the finite output coupling also contributes to the reduction of the thermal effects in crystal.

This book was released on 2014 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-power, continuous-wave (cw) optical parametric oscillators (OPOs), from the ultraviolet (UV) and visible to the near- and mid-infrared (IR) wavelength range, are of interest for a variety of applications such as spectroscopy, trace-gas detection and remote sensing. As such, it is desired to investigate OPOs and different frequency conversion techniques, to cover the spectral regions that are inaccessible to lasers, and that too in a compact and low-cost design. This thesis presents the development of high-power cw OPOs, and frequency conversion sources, spanning the UV to mid-IR spectral range, employing different designs, experimental configurations and nonlinear crystals, making them compact and cost-effective. Commercial high-power cw lasers at 1940 nm, 1064 nm and 532 nm have been exploited as the pump sources, in the work presented in this thesis. We have demonstrated a fiber-based cw source at 970 nm, in a simple and practical design. Using direct single-pass second-harmonic-generation (SHG), 13.1 W of output power at 970 nm has been generated in a high-beam-quality, narrow-linewidth, linearly-polarized beam. Further, a technique based on the use of an antiresonant ring (ARR) interferometer for the attainment of optimum output coupling in a cw singly-resonant OPO has been investigated. The technique was deployed in a Yb-fiber-laser-pumped cw OPO based on MgO:PPLN. To extend the tunability of the 1-μm-pumped OPO from the mid-IR to near-IR, SHG of the intracavity signal has been performed in fanout-grating MgO:sPPLT. This compact cw source, tunable across 775¿807 nm, provides >3 W of near-infrared power across 56% of SHG tuning range, in high spatial beam quality. We have also generated output in the UV, down to 355 nm, using single-pass configuration based on sum-frequency-generation of fundamental at 1064 nm and the generated SHG at 532 nm, in BiB3O6. Further, we demonstrated an architecture comprising two cw OPOs coupled together with an ARR interferometer, generating two pairs of signal and idler wavelengths, that can be independently and arbitrarily tuned to indefinitely close spacing, through degeneracy, and beyond, across the wavelength range of 870-1370 nm. The OPOs, based on identical MgO:sPPLT crystals, were pumped by a single cw laser at 532 nm. On the other hand, we also demonstrated active mode-locking of cw OPOs using direct low-frequency electrooptic phase-modulation (EOM), opening up the possibility of avoiding the need for ultrafast laser sources and synchronous pumping. We have generated picosecond pulses in doubly- and singly-resonant configuration. Also, a technique based on the deployment of the EOM in combination with an ARR interferometer internal to the cw OPO has been investigated for active modelocking.
