摘要CTS-0113206 R。Lucht，Texas A M UniversityComponents被收购用于开发可调谐、高分辨率光学参量振荡器（OPO）激光源。 该系统的特点是谐振，电子锁定环形振荡器腔，注入种子与可调谐二极管激光辐射。 用于OPO系统的泵浦源是Q开关注入种子Nd：YAG激光器。 除了用作OPO腔的泵浦源外，YAG激光器的基波（1064 nm）和谐波（532 nm、355 nm和266 nm）激光辐射还用于和频产生（SFG）过程，以将OPO的近红外输出转换为可见光或紫外辐射。 该光源将大大提高各种激光诊断技术的适用性和准确性。 具体实例包括羟基和一氧化氮的紫外偏振光谱（PS）、碳原子的放大受激发射（ASE）和氢分子的相干反斯托克斯拉曼散射（汽车）。

AbstractCTS-0113206R. Lucht, Texas A&M UniversityComponents are acquired for development of a tunable, high-resolution optical parametric oscillator (OPO) laser source. The system features a resonant, electronically locked ring-oscillator cavity that is injection-seeded with tunable diode laser radiation. The pump source for the OPO system is a Q-switched injection-seeded Nd:YAG laser. In addition to serving as the pump source for the OPO cavity, the fundamental (1064 nm) and harmonic (532 nm, 355 nm, and 266 nm) laser radiation from the YAG laser is used in sum-frequency generation (SFG) processes to convert the near infrared output of the OPO into visible or ultraviolet radiation. This source will greatly improve applicability and accuracy of a wide variety of laser diagnostic techniques. Specific examples include ultraviolet polarization spectroscopy (PS) of hydroxyl and nitric oxide, amplified stimulated emission (ASE) of the carbon atom, and coherent anti-Stokes Raman scattering (CARS) of the hydrogen molecule.
