A SIMPLE KEY FOR KYW CRYSTAL UNVEILED

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is quite huge in comparison with that of Yb:YAG. This allows for broad wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values well down below a hundred fs are realized with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared
