摘要

A high power continuous-wave(CW) 914-nm Nd:YVO_4 laser at room temperature is presented.Using an end-pumped structure and employing an 808-nm diode-laser as the pump source,the maximum output power of 15.5 W of the 914-nm laser is achieved at the absorbed pump power of 40.2 W,with a corresponding average slope efficiencyη_s=65.6%.To the best of our knowledge,this is the highest output power of diode-pumped 914-nm laser.A beam quality factor M~2=2.8 at the output power of 15 W is measured by using the tra...
