AN UNBIASED VIEW OF KYW CRYSTAL

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big in comparison with that of Yb:YAG. This permits for wide wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values effectively underneath one hundred fs are accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
