| 中文摘要 | 随着激光二极管(LD)和光纤激光器的迅猛发展，低浓度掺Ho3+谐振泵浦激光晶体引起人们的极大关注。H矿+激光器的输出波长在2um附近，处于大气窗口，为遥感探测以及光电对抗提供了有利的工具，同时也是相干多普勒测风雷达、差分吸收雷达和激光测距机等系统的理想光源。YAP晶体具有优异的热力学性能，热导率与常见的YAG晶体接近，能抑制激光运转过程产生的热致双折射和热透镜效应，并能输出线偏振激光。LSO晶体因其独特的低对称性单斜晶体结构，Lu3+扭曲的低对称双格位特性，为掺杂离子提供较强的晶体场，有利于掺杂离子产生大的Stark能级分裂。 |
| 英文摘要 | With the development of LD and fiber laser, resonantly pumped laser crystals with low Ho3+ concentration attract。lot of interest. Ho3+ laser around 2um is just within atmospheric window, making it an effective tool for remote sensing and photoelectric countermeasures. Ho3+ laser has become an ideal laser source for coherent Doppler lidar, differential absorption lidar and laser range finder. YAP has good optical, thermal, and mechanical properties similar to those of YAG. Its natural birefringence overwhelms the thermally induced birefringence and bifocusing usually observed in YAG crystal, and polarized laser can be obtained. As a monoclinic biaxial crystal, the lutetium orthosilicate LSO features low symmetry and multi-type of distorted substitutional sites, which provide strong local crystal-field strength, making it favorable for large Stark splitting levels of the rare-earch dopants. |
