半导体激光泵浦Nd:YVO4激光器的1.34 μm输出特性
Characteristics of LD Pumped Nd:YVO4 Laser Operating at 1.34 μm
摘要
报道了半导体激光泵浦Nd:YVO4激光器在1.34 μm的输出特性,当入射的泵浦光功率为515 mW时,最大1.34 μm激光输出功率达157 mW,光-光转换效率为30.5%;研究了激光器的纵模特性及弛豫噪声与泵浦功率的关系;发现不同的纵模具有各自不同的弛豫振荡频率。
Abstract
The characteristics of a LD pumped Nd:YVO 4 laser operating at 1.34 μm are reported. The maximum output power of 157 mW with a optical to optical conversion efficiency of 30.5% has been obtained at the incident pump power of 515 mW. Variations of the longitudinal modes and the amplitude noise power spectrum with the incident pump power have been studied. The phenomenon that each longitudinal mode has its own relaxation oscillation frequency has been found.
