NOT KNOWN DETAILS ABOUT KYW CRYSTAL

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is very substantial compared with that of Yb:YAG. This allows for large wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values nicely underneath one hundred fs are already accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) cr
