イッテルビウムファイバ増幅モジュール
高いポインティング安定性と低い非線形特性により、柔軟で汎用性の高いレーザ構成を実現します。同一のaeroGAIN-BASEで、フェムト秒、ピコ秒、ナノ秒パルスの増幅に対応し、用途に応じて高効率な周波数変換が可能です。aeroGAIN-BASEは、最適な性能を発揮するため、出力側のエンドキャップから逆方向に励起する方式を採用しています。エンドキャップおよびゲインファイバの終端部分は水冷ハウジングに搭載されており、高い性能と長寿命を実現します。
aeroGAIN-BASEは、クリーンルームで組み立ておよび試験を行っています。また、aeroGAIN-BASEは、安全な輸送を目的としたツールプレートに搭載されており、エンドキャップアセンブリを保護するカバーも付いています。このツールプレートは、実験室でのマウントとしても使用可能です。aeroGAIN-BASEの設計は、出力55 Wで25,000時間の連続動作を含む様々な長期試験により、産業用途における長時間連続動作においても、高い信頼性が確認されています。個別のOEMシステムにおける製品寿命は、励起パワー、励起波長、冷却効率などの条件に依存します。システム設計のサポートについてはお問い合わせください。
