Abstract
Some types of novel absorbers for solidstate laser passive Qswitching developed in recent years are introduced, such as Cr4+ doped series,Cr,Nd∶YAG selfQswitching laser crystal,absorbers for passive Qswitching eyesafe lasers, GaAs absorber, semiconductor saturable absorption mirror.The principle, application and exploratory development of semiconductor saturable absorption mirrors for passive Qswitching of solidstate lasers and fiber lasers are emphasized.
