KYW CRYSTAL - AN OVERVIEW

The get bandwidth e.g. of Yb:KGW and Yb:KYW is very significant as opposed with that of Yb:YAG. This allows for wide wavelength tunability and for much shorter pulse durations from method-locked lasers. Values properly under a hundred fs happen to be obtained with passive manner locking.The comparison with Eyeglasses is acceptable since the large
