KYW CRYSTAL - AN OVERVIEW

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in contrast with that of Yb:YAG. This permits for wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values very well below one hundred fs have already been realized with passive manner locking.The comparison with Eyeglasses is appropr
