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 quite big in contrast with that of Yb:YAG. This allows for wide wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values very well down below one hundred fs are already attained with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal,
