KYW CRYSTAL - AN OVERVIEW

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is very huge in comparison with that of Yb:YAG. This allows for broad wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values well below a hundred fs have already been reached with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal
