KYW CRYSTAL OPTIONS

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather large in contrast with that of Yb:YAG. This allows for broad wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values effectively under one hundred fs are already reached with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
