We report herein an efficient eye-safe Raman laser, which is based upon Nd:YVO₄₋YVO₄ and in-band pumped by a wavelength-locked laser diode array at 878.6 nm. By virtue of mitigated thermal load and improved pump absorption, a maximum average output power of 5.2 W at 1525 nm is obtained under the incident pump power of 30.6 W with the pulse repetition frequency of 140 kHz, corresponding to an optical efficiency of 17.0%.
我们在此报告一种高效的人眼安全拉曼激光器，它基于Nd:YVO₄ - YVO₄，并由波长锁定的激光二极管阵列在878.6 nm进行带内泵浦。由于减轻了热负载并提高了泵浦吸收，在30.6 W的入射泵浦功率和140 kHz的脉冲重复频率下，在1525 nm处获得了5.2 W的最大平均输出功率，对应的光效率为17.0%。
