A SIMPLE KEY FOR KYW CRYSTAL UNVEILED

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in contrast with that of Yb:YAG. This enables for wide wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values perfectly below 100 fs have already been reached with passive method locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) c
