Everything about KYW Crystal
The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly substantial when compared with that of Yb:YAG. This permits for large wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values perfectly down below a hundred fs are actually achieved with passive manner locking.The Yb-doped potassium yttrium tungstate
