製品詳細
低ノイズ用途に最適
Koheras ADJUSTIKシリーズは、ベンチトップ型システムであり、セットアップに時間をかけることなく、科学研究用のツールとして使用したい研究室向けに、迅速に導入可能です。
本シリーズは、当社のKoheras BASIKモジュールシード技術をベースとしており、出力パワーのアップグレードにも対応しています。システムには、波長、出力パワー、RIN抑制などのレーザパラメータをPC上で制御および読み出しができる、ユーザーフレンドリーな専用制御ソフトウェア (CONTROL)が付属しています。
ADJUSTIKレーザは、レーザノイズが重要となる計量やコヒーレントセンシングなど、あらゆる種類の低ノイズ用途に最適です。ADJUSTIK HP T20は、量子ビット操作、量子センシング、シンパセティック冷却などの量子用途向けに、特にバリウムの6S–5D遷移を想定して設計されています。
