| 摘 要： | 大多数小型手持式激光测距仪均采用平行平面谐振腔结构的Nd:YAG激光器作为测距光源,因其激光器的峰值功率不高,激光束散角差,重复工作频率低而使测距仪的性能受到一定限制。我们采用能同时压缩脉宽和束散角的平凸型非稳腔和热效率高的新型双掺(Ce,Nd):YAG晶体,装调出的激光器获得了18.6mJ能量,5ns脉宽,0.6mrad束散,峰值功率3.7MW的激光单脉冲输出。

Auto-collimated output (Ce, Nd)：YAG laser with a plane-convex resonator |
| |
| Abstract: | The lower peak power, the large divergence angle and the low repetition frequency of the Nd:YAG laser with the parallel plane resonator, which is used as a ranging light source in most small sized handheld laser rangefinders, restrict the performances of those rangefinders to a certain extent. A plane-convex unstable resonator by which both pulse width and divergence angle can be decreased and a new high thermal efficiency Ce and Nd doped YAG crystal have been designed for a laser which a single laser pulse output with an energy of 18.6mJ, a pulse width of 5 ns,a divergence angle of 0.6 mrad and a peak power of 3.7 MW has been obtained. |
