DETAILED NOTES ON KYW CRYSTAL

The attain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely massive compared with that of Yb:YAG. This enables for broad wavelength tunability and for Substantially shorter pulse durations from mode-locked lasers. Values nicely under a hundred fs are actually accomplished with passive mode locking.The Yb-doped potassium yttrium tungstate (Yb:KYW)
