在半导体激光器高功率抽运的镱、钠共掺氟化钙(Yb,Na:CaF_2)激光器中,通过对晶体的负热透镜效应的数值模拟,进行激光器腔型的调节和优化,使得该激光器在采用2%的耦合输出镜和吸收抽运功率为7.8 W的条件下,获得了脉冲宽度为190 fS、平均输出功率为503 mW、中心波长为1034 nm、重复频率为82.4 MHz的连续锁模脉冲序列.如果计算晶体表面反射等其他形式的泄漏输出,激光器的总平均输出功率为905 mW.
In the Ytterbium and Sodium co-doped calcium fluoride (Yb, Na: CaF 2) laser with high power pumping of semiconductor lasers, the laser cavity type is adjusted and optimized by numerical simulation of the negative thermal lens effect of the crystal, so that the laser Under the condition of a 2% coupled output mirror and an absorption pumping power of 7.8 W, a continuous mode-locked mode with a pulse width of 190 fS, an average output power of 503 mW, a center wavelength of 1034 nm and a repetition frequency of 82.4 MHz Pulse Sequences. If you calculate other forms of leakage output, such as crystal surface reflections, the total average laser output power is 905 mW.
