Description
図1は、本発明の第1実施形態に係る波長変換型空間光変調装置(以下、光変調装置という)の構成を概略的に示す図である。本実施形態の光変調装置1Aは、空間光変調部10と、波長変換部20と、像転写光学系30とを備えている。
図15は、上記実施形態の像転写光学系30の変形例として、像転写光学系33の構成を示す図である。この像転写光学系33は、単一のレンズ34を含んで構成されており、この単一のレンズ34によって、空間光変調部10の位相変調面10aと波長変換部20の光入射面(波長変換面)20aとが、互いに光学的に共役な系となるように結合されている。具体的には、レンズ34の焦点距離f、位相変調面10aとレンズ34との距離f1、及びレンズ34と波長変換面20aとの距離f2が、以下の関係式(1)を満たすように設定されている。
光変調装置1Bは、図3に示された像転写光学系30に代えて、図15に示された像転写光学系33を備えても良い。この場合であっても、上記実施形態の効果を好適に得ることができる。
図16は、本発明の第2実施形態に係る光変調装置の構成を概略的に示す図である。本実施形態の光変調装置1Cは、第1実施形態の光変調装置1Aと同様に、空間光変調部10と、波長変換部20と、像転写光学系30とを備えている。この光変調装置1Cにおいて光変調装置1Aと異なる点は、波長変換部20を構成する非線形光学結晶が、空間光変調部10から出力された変調レーザ光L2とは別の光束L4を変調レーザ光L2とともに光入射面に受け、変調レーザ光L2と光束L4との和周波または差周波を発生することにより紫外レーザ光L3を生成する点である。このような構成によって、変換後に利用可能な波長の数を増やすとともに、波長変換効率の低下を効果的に回避することができる。
