Radiation from a fiber coupled diode (core diameter 0.4 mm, N.A. 0.3) is coupled into Tm5% at.,Ho(0.5% at.∶GdVO4 crystal by a pair of achromatic lens for end pumping. Output power of 3.6 W at 2.048 μm is obtained under pump power of 14 W and emission wavelength of 794 nm. The optical-optical conversion efficiency is 25.7% and slope efficiency is 26.6%.
