【摘要】 研究了石榴石激光器中超短脉冲的形成,染料的吸收系数 x₀、染料的饱和功率I_s。激光介质中的光束横截面积与染料中的光束横截面积比 A 对被动锁模过程的影响。研究的激光在1.06微米产生带宽极限的脉冲,光谱分布和时间分布都是高斯函数,单个脉冲的宽度可调,从20微微秒到200微微秒。更多还原

【Abstract】 An investigation was made of the formation of ultrashort pulse trains in an YAG laser,and the effects on the passive mode locking process of the initial dye absorption coefficient x_o,the saturable power of the dye solution I_s,and the ratio of the beam cross section in the laser medium to the beam cross section in the absorber.The laser under investigation produces bandwidth-limited output pulses at 1.06μm,with spectral profile and temporal profile in Gaussian function.Single pulses can be adjusted from 20ps to 200ps.更多还原
