摘要
报道了基于V:YAG可饱和吸收体的1.34 μm被动调Q锁模Nd:YVO4激光器。采用直腔结构,使用透过率为10%的输出镜,在LD端面泵浦的情况下,实现了重复频率高达2.6 GHz的1.34 μm调Q锁模运转。Nd:YVO4晶体中,Nd3+离子掺杂质量分数为0.2%V:YAG晶体的初始透过率为83%。在泵浦功率为11 W时,1.34 μm调Q锁模激光的最大平均输出功率为308 mW,光-光转换效率为2.8%。
Abstract
A passively Q-switched mode-locked Nd:YVO 4 laser based upon V:YAG saturable absorber at 1.34 μm is reported. In the case of LD end-pumped, 1.34 μm Q-switch mode-locked pulse operation with a repetition rate up to 2.6 GHz is realized by using linear cavity structure at output mirror with 10% transmittance. The Nd3+ concentration of the Nd:YVO 4 crystal is 0.2%, and the initial transmittance of V:YAG is 83%. When the incident pump power is 11 W, the maximum average output power of the 1.34 μm Q-switched mode-locked laser is 308 mW with a light-light conversion efficiency of 2.8%.
