Nd:YAG高能量納秒激光器Lotis TII調Q激光器
LOTIS TII Q開關Nd:YAG脈沖激光器家族可為用戶提供各種脈沖輸出能量，脈沖寬度從5納秒到24納秒，重復頻率從1Hz到100Hz。與此同時，不同型號的激光器還包含有內置2倍頻，3倍頻，4倍頻，甚至5倍頻輸出。對沒有內置倍頻晶體的型號，有外置倍頻晶體可供選擇，以提供所需高倍頻激光脈沖輸出。有些型號的激光器應用了可變反射系數的反射鏡，使其具有更好的光束質量，更高的諧波轉換效率。
---- 新的激光頭設計使得波長切換（1064nm、532nm、355nm、266nm）更加簡單，可以通過電腦或者手動控制；
---- 對非線性&調Q晶體嚴格的溫度控制，以及特殊的激光諧振腔設計，使得激光器輸出參數穩定；
---- 增加高能量的三階非線性波長（355nm）和集成的五階非線性（213nm）可選。
