6.5 W LD-pumped 914 nm Nd:YVO4 laser
摘要
Abstract
As an important laser active medium, Nd: YVO4 is widely used in LD end-pumped solidstate lasers due to its large stimulated emission cross section, very strong broad absorption band at 809 nm and polarized emission,etc, and it has three useful stimulated emission spectra of 1 064 nm,1 342 nm and 914 nm but the quasi three level of 914 nm spectum and the low thermal conductivity of YVO4 crystal limit the development of its high power laser output. An efficient high power LD-endpumped continuous-wave (CW) Nd: YVO4 laser has been developed by restraining the high gains at wavelengths of 1 064 nm and 1 342 nm with a simple folded cavity and suitable medium film applied on its three mirrors. An output power of 6.5 W, slope efficiency of 37.9% and optical-to-optical conversion efficiency of 22.4% can be achieved when the pump power is 29 W.关键词
