Abstract

A spectroscopic characterization of Tm-Ho:KYF4 crystals with different doping levels is presented. A comparative investigation based on diode-pumped 2-μm laser experiments shows that the best trade-off in terms of cw output power characteristics and wavelength tuning ranges is obtained with 5% Tm-0.5% Ho active crystal.
