摘要

提出了一种基于受激布里渊散射（SBS）技术的2 μm短脉冲光学参量振荡器（OPO）。SBS介质选用FC-770型电子氟化液。设计并构建了1 μm的亚纳秒级泵浦源，实现了脉冲宽度约为800 ps的亚纳秒级激光输出。通过泵浦ii型非临界相匹配KTiOPO4 （KTP）晶体，在2.1 μm简并点，工作频率为100 Hz，单脉冲泵浦能量为10.11 mJ，实现了1.052 mJ的参量激光输出。相应的泵浦光到参数光的转换效率为10.4%，输出脉冲宽度约为1.9 ns。

Short-Pulse 2 μm optical parametric oscillator based on stimulated Brillouin scattering technology

In this paper, a short-pulse 2 μm optical parametric oscillator (OPO) based on stimulated Brillouin scattering (SBS) technology was presented. FC-770 electronic fluorinated fluid was selected as the SBS medium. A sub-nanosecond pump source at 1 μm was designed and constructed, achieving a sub-nanosecond laser output with a pulse width of approximately 800 ps. By pumping a type-II non-critical phase-matched KTiOPO₄ (KTP) crystal, we achieved a parametric light laser output of 1.052 mJ at the 2.1 μm degeneracy point, under a working frequency of 100 Hz and a single-pulse pump energy of 10.11 mJ. The corresponding conversion efficiency from pump light to parametric light was 10.4 %, and the output pulse width was approximately 1.9 ns.

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
