AN UNBIASED VIEW OF KYW CRYSTAL

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very large compared with that of Yb:YAG. This enables for vast wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values effectively underneath a hundred fs have already been realized with passive manner locking.The Yb-doped potassium yttrium tungstate (Y
