Abstract

固体増幅器５０に対する励起光のパワーが維持された状態で、装置１からパルス光の出力を許容する出力許容状態のときに種光源１０をゲインスイッチング法でパルス発振させるパルス発振モードで駆動し、装置１からパルス光の出力を停止する出力停止状態のときに種光源１０を連続発振させる連続発振モードで駆動するとともに、出力停止状態で固体増幅器５０から出力される光の平均パワーが、出力許容状態で固体増幅器５０から出力される光の平均パワーと略等しくなるように、連続発振モードで種光源１０から固体増幅器５０に入力されるレーザ光のパワーを調整する制御部１００を備え、励起用光源を停止または調整することなく一時的にパルス光の出力を停止させ、出力再開直後のビーム伝播特性の劣化を回避可能なレーザ光源装置。
