Abstract :
An experimental investigation on the laser performance of an α-oriented Tm,Ho: YAIO3 crystal end-pumped by a wavelength tunable Ti:Sapphire laser is presented in this paper. Single- and dual-wavelength operations of Tm,Ho:YAIO3 lasers have been investigated in detail. Maximum output powers of 890mW at 2119nm, 836mW at 2103nm and 487mW at 2130nm for the α-oriented Tm,Ho:YAIO3 crystal have been obtained, corresponding to optical conversion efficiencies of 32% and 31% and 18% in terms of absorbed pump power, respectively. The maximum slope efficiency reaches 45.9% when the laser runs at 2119nm.
