众所周知,He-Se激光器具有广泛的应用前景.但由于其输出功率与工作电流、Se离子浓度有明显的依赖关系,使用中应保持工作电流和Se离子浓度均恒定于最佳值;又由于工作时光腔窗口与工作区温差很大,操作不慎易使Se蒸气凝结于较冷的窗口而严重影响激光器输出功率和寿命,因此使用中还必须严格遵从一定的操作程序以免窗口污染.这给实际应用带来很大不便.为此我们研制了具有自动联锁操作和恒温恒流特性的专用电源,以简化操作手续和确保激光器安全、稳定地工作.
As we all know, He-Se laser has a wide range of applications, but because of its output power and current, Se ion concentration has a clear dependence on the use should be kept working current and Se ion concentration are constant at the best value; Time window and the work area temperature window is very large, accidentally easy to make Se vapor condensation in the cooler window and seriously affect the laser output power and life expectancy, so the use must also strictly follow certain procedures to avoid window pollution.This gives the actual Application has brought great inconvenience.To this end we have developed a special power with automatic interlocking operation and constant temperature and constant current characteristics to simplify the operation procedures and to ensure the safe and stable operation of the laser.
