Abstract

What is to the authors' knowledge the first experimental demonstration of a nonresonant cw Raman laser pumped by a tunable external-cavity diode laser (ECDL) is presented. The ECDL is phase-frequency locked to a high-finesse Raman laser cavity containing diatomic hydrogen (H(2)) by the Pound-Drever-Hall locking technique. The Stokes lasing threshold occurs at a pump power of 400 +/- 30 muW, and a maximum photon conversion efficiency of 12.0 +/- 1.3% is achieved at 1.6 mW of pump power. A 40-nm tuning range of the cw Stokes emission, 1174-1214 nm, is obtained by tuning of the wavelength of the ECDL pump source.

摘要

本文展示了据作者所知首个由可调谐外腔二极管激光器（ECDL）泵浦的非共振连续波拉曼激光器的实验演示。通过庞德 - 德雷弗 - 霍尔锁定技术，将ECDL的相位 - 频率锁定到一个包含双原子氢（H₂）的高精细度拉曼激光腔。斯托克斯激光阈值出现在400±30 μW的泵浦功率下，在1.6 mW的泵浦功率下实现了12.0±1.3%的最大光子转换效率。通过调谐ECDL泵浦源的波长，获得了1174 - 1214 nm的连续波斯托克斯发射的40 nm调谐范围。
