连续波Ti:Sapphire激光器具有很宽的波长调谐范围(700-1000 nm),并发现它是许多基础研究领域(尤其是各种光谱学应用)的有用工具。
波长调谐是由双折射Lyot滤光片进行的,可以手动控制,也可以通过USB连接到PC的步进电机来控制。可以选择将两个标准具放入腔中,以将生成的辐射的线宽缩小到2 GHz。
CW Ti:Sapphire激光器需要由532 nm的CW DPSS泵浦激光器泵浦。我们公司提供不带泵浦激光器的振荡器,以及集成泵浦激光器且泵浦功率从2 W到8 W不等的振荡器。
提供可选的光纤耦合修改。辐射被引导到纤芯直径为4 um的光纤中。光学方案允许通过倒装安装架在自由空间和光纤输出之间轻松切换。
