THE KYW CRYSTAL DIARIES

The get bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from mode-locked lasers. Values properly down below a hundred fs happen to be attained with passive mode locking. This one of a kind characteristic of ultrafast p
