Passively mode locked femtosecond Tm:Sc2O3 laser at 2.1 mu m
MetadataShow full item record
We report on the passive mode locking of a Tm3+:Sc2O3 laser at 2.1 mu m using a semiconductor saturable absorber mirror based on InGaAsSb quantum wells. Transform-limited 218 fs pulses are generated with an average power of 210 mW. A maximum output power of 325 mW is produced during mode locking with the corresponding pulse duration of 246 fs at a pulse repetition frequency of 124.3 MHz. A Ti:sapphire laser is used as the pump source operating at 796 nm. (C) 2012 Optical Society of America
