摘要
报道了一种由波长锁定878.6 nm半导体激光器抽运Nd:YVO4晶体的1064 nm激光器,当晶体吸收7.41 W的抽运功率时获得了5.75 W的1064 nm激光输出,相对于吸收功率的斜率效率为80.2%,光光转换率为77.6%,并且对波长锁定878.6 nm,非波长锁定的808 nm,878.6 nm抽运的激光器的温度特性进行了研究,结果表明利用波长锁定878.6 nm作为抽运源的激光器在10 ℃~40 ℃的温度变化范围内具有很好的输出稳定性。
Abstract
A Nd:YVO4 laser at 1064 nm pumped by a wave-locked 878.6 nm laser diode is achieved. An output power of 5.75 W at 1064 nm for an absorbed pump power of 7.41 W, corresponding to an optical efficiency of 80.2%, optical to optical efficiency of 77.6%. The temperature characteristics of wave-locked 878.6 nm, wave-unlocked 808 nm and 878.6 nm pump laser are also researched. The result shows that wave-locked 878.6 nm pumped Nd:YVO4 laser has excellent output stability when the temperature varies from 10 ℃ to 40 ℃.
