The gain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for huge wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values perfectly underneath 100 fs happen to be accomplished with passive manner locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) c… Read More
