Abstract

A multisegmented Nd:YVO4 laser operating at 1342 nm that is in-band pumped by a wavelength-locked 878.6 nm laser diode is reported here. We achieve an output power of 12.45 W at 1342 nm for an absorbed pump power of 35.6 W, corresponding to an optical-to-optical efficiency of 34.9% and a slope efficiency of 36.1%. To the best of our knowledge, it is the highest optical-to-optical efficiency of Nd:YVO4 lasers operating at 1342 nm with an output power more than 10 W.

摘要

本文报道了一种多段式掺钕钒酸钇（Nd:YVO4）激光器，其工作波长为1342 nm，由波长锁定在878.6 nm的激光二极管进行带内泵浦。在吸收泵浦功率为35.6 W的情况下，我们在1342 nm处实现了12.45 W的输出功率，对应的光光效率为34.9%，斜率效率为36.1%。据我们所知，这是输出功率超过10 W的工作在1342 nm的Nd:YVO4激光器中最高的光光效率。
