単一周波数ファイバレーザ
Koheras MIKROシリーズ
特長
- OEM向けのコンパクトサイズ
- 堅牢な単一周波数動作
- 低位相ノイズ、狭線幅
- 高い波長安定性
- 偏波保持および高速変調オプション
製品詳細
標準波長は1550 nmですが、MIKRO は1535 nm 〜 1580 nmの範囲で任意の出力波長を選択可能です。オプションで 1064 nm付近の波長にも対応します。本レーザは、温度制御により波長調整ができ、外部安定化などための高速波長変調と組み合わせることもできます。
レーザは偏波保持 (PM)出力と非PM出力のいずれにも対応しています。
容易な制御を実現するため、MIKROにはオプションとしてUSBインターフェースキットが用意されており、ユーザーフレンドリーな専用制御ソフトウェア (CONTROL)のGUIで制御することができます。
