A SIMPLE KEY FOR KYW CRYSTAL UNVEILED

The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very massive compared with that of Yb:YAG. This allows for huge wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values perfectly under 100 fs are already realized with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in compar
