KYW CRYSTAL OPTIONS

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant when compared with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values well beneath 100 fs are already accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
