TOP KYW CRYSTAL SECRETS

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is quite massive in comparison with that of Yb:YAG. This allows for broad wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values well under 100 fs have already been realized with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in com
