LD端面抽运Yb∶YAG/LBO537.8nm绿光激光器
Laser diode end-pumped Yb∶YAG/LBO 537.8nm green laser
摘要
为了研究Yb∶YAG激光器的倍频输出特性,采用LD端面抽运掺杂原子数分数为0.1的Yb∶YAG薄片激光晶体(?4mm×1mm)、LBO(LiB3O5)腔内倍频进行了实验研究。在LD抽运功率为1.37W时,通过调节LBO的放置角度,实现了频率选择,并获得了最高功率为3.1mW的537.8nm的基模连续激光输出,光斑椭圆度为0.94。结果表明,采用Yb∶YAG激光晶体,通过LBO腔内倍频可以获得稳定的高光束质量的537.8nm激光输出。
Abstract
In order to obtain the output characteristic of a frequency doubled Yb∶YAG laser,a 0.1 atom fractiom doped Yb∶YAG microchip crystal(?4mm × 1mm)end-pumped by laser diodes,and a LBO crystal were employed. With the pump power of 1.37 W,frequency selected of nonlinear crystal was realized by tuning the lying angle of LBO 3.1 mW TEM00 continuous wave laser at 537.8nm was obtained. The ellipticity of the output beam was 0.94.The results show that high-quality 537.8nm green laser can be obtained with intra-cavity frequency double crystal LBO and Yb∶YAG laser crystals.
