KYW CRYSTAL NO FURTHER A MYSTERY

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is very significant when compared with that of Yb:YAG. This permits for broad wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values very well below 100 fs have already been realized with passive manner locking.The comparison with glasses is suitable since t
