摘要
以激光二极管端面泵浦固体激光器为研究对象,在不同的泵浦光空间分布下,通过数值求解速率方程,得到腔内横模分布的变化规律,分析了对光束质量的影响。结果表明,泵浦光半径越接近振荡光半径,基模所占比率越大;而泵浦功率对横模分布的影响不大。
Laser diode end-pumped solid laser as the research object,with different spatial intensity distribution of the pump light,by numerical solving the rate equation,the variation regularity of the transverse mode distribution in the cavity are obtained.Then the influences of the spatial intensity distribution of the pump light on the beam quality are analyzed.The results show that as the radius of the pump light close to the radius of the oscillating light,the percentage of the fundamental mode will increase,while the influences of pump power on the mode distribution is not very obvious.
