TETA Yb再生放大器系統
特點：
超小體積
剛性設計
一體化方案設計
脈沖能量>200 μJ
脈寬<300 fs
光束質量好
良好的光束指向性和長時間功率穩定性
TETA是鐿固體激光器系統。系統由一個內置光纖種子振蕩器，光纖脈沖展寬器，法拉第隔離器，基于CPA的直接半導體泵浦再生放大器，附加脈沖提取器和脈沖壓縮器組成。所有的器件集成在一個熱穩定的箱體內，保證了穩定性和交鑰匙運行。額外內置普克爾盒可以實現瞬間關閉輸出輻射，以及用戶控制輸出重復頻率。而且，普克爾盒可以精確提取脈沖，控制發射脈沖數（突發模式）和輻射的時間周期。TETA系統可以配備二次諧波和四次諧波產生器，以及Compulse毛細管壓縮器，將脈寬降低到30 fs，轉換效率>50 %。
TETA激光器系統是可靠靈活的輻射源，用于飛秒微加工系統，太赫茲成像，OPA泵浦，遠程遙感和超快光譜技術。
