製品詳細
優れたシングルモード増幅
aeroGAIN-RODは、従来マルチモードシステムで対応していた出力領域において、シングルモードでの増幅を実現します。シングルモード増幅には、マルチモードシステムと比較して以下の利点があります。
・高い出力安定性
・優れたビーム品質
・ファイバの強い曲げによるモード制御が不要
優れたモード品質と容易な結合特性により、aeroGAIN‑RODは高出力アンプの増幅媒体として適しています。アルミニウム筐体により、OEM用途や科学実験室でのセットアップにおいて、取り扱いや設置が容易に行えます。クイックカップリングを備えた一体型水冷機構を採用し、効率的な熱管理と長期安定動作を実現しています。励起光は、高い信頼性、高い損傷閾値、および高NA (開口数)を備えたエアクラッド技術を用いて導光されます。本モジュールには、高出力対応のARコート付きエンドキャップを標準装備しています。
