HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD KYW CRYSTAL

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is rather substantial when compared with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values effectively under 100 fs have been attained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:K
