KYW CRYSTAL OPTIONS

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is extremely huge in comparison with that of Yb:YAG. This enables for vast wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values well below a hundred fs are actually accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal
