免调试固体激光器的研究

描述了一种新型的免调试激光装置.它采用定向棱镜作为谐振腔的全反镜,在固体激光器中安装后不经调试就能实现激光运行,它具有抗失调能力强、远场光场能量集中、发散角小的特点,角度失调允量±20°,棒轴平移量为D/4,发散角小于3mrad.在100Hz高重复频率运行时,单脉冲Cr4+:YAG晶体被动调Q输出能量达到300mJ,且光场分布均匀.

Avoidance adjust solid state laser

A innovatory avoidance adjust solid state laser was demonstrated.It used the directional prism as a reflector of the resonant cavity.With the prism reflector,the laser operats normally without special adjustment.The stability is the highest than other rasonant cavity.The divergence angle of laser beam is small.The laser energy of far-field is focus.The deflection angle allowed of the reflector is of ±20°.The laser rod shift of D/4 is allowed which D is the diameter of the laser rod.The divergence angle of laser beam is small than 3 mrad.The laser output energy 300mJ/pulse in the high repeatition of 100Hz with a Cr⁴⁺:YAG crystal as passive Q-switch,and the laser field distribution is homogeneous.
