Abstract
【解決手段】エンクロージャを備えたレーザ増幅器モジュールは、入力窓と、入力窓に光学的に結合され、第1の面に配置されたミラーと、エンクロージャの第1の端部に隣接した光学増幅路に沿って配置された第1の増幅器ヘッド129とを備える。また、レーザ増幅器モジュールは、エンクロージャの第2の端部に隣接した光学増幅路に沿って配置された第2の増幅器ヘッド136と、光学増幅路に沿って配置されたキャビティミラー140、150とを備える。

Description
(連邦政府の支援による研究又は開発によりなされた発明に対する権利に関する説明)
熱複屈折の悪影響により、一部のシステム設計者はブルースター角設計を使用するようになっている。増幅器ヘッド129、136を通る第1の増幅パスの後、ビームがキャビティミラー140に画像リレーされて、円偏光が左から右へ修正される(前述した左利きを想定)。一部の実施形態では、ミラー140は増幅ビームからの歪みを低減又は除去するように動作可能な変形可能ミラーである。図示したように、リレーテレスコープが、増幅器ヘッド136の出口回転ミラーとキャビティミラー140との間の光学路に沿って配置される。
