Abstract
Description
本明細書では、「混合」または「波の混合」とは任意の和周波発生(SFG)、差周波発生(DFG)、四波混合(FWM)または類似の非線形の処理および原理を意味する。
対照的に、差周波発生(DFG)プロセスでは、遠赤外および中赤外の波長が生成できる。同じNd:YAGレーザ媒体に対し、差周波発生(DFG)で結果として得られる波長は、5504nm,3345nm,8530nm,6002nm,7557nmおよび20252nmである。
異なる波長の2つのビームの間の良い出力比率の設定は、和周波発生(SFG)または差周波発生(DFG)プロセスで高い効率を得るために非常に重要である。
