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,...
Using a novel broadband Yb-doped crystal close-loop cooled at -130degC we demonstrate a 2-6-W multi-kilohertz amplifier delivering sub-200-fs pulses with energies up to 2 mJ. This technology is straightforwardly scalable toward a kHz-repetition-rate multi-mJ output.
Absorption, photoluminescence spectra and CW lasing parameters of an Yb3+- and Na+-codoped CaF2 laser crystal are measured in the temperature range from 5 K to 290 K. The crystal appears to be a promising host for broadband multi-mJ kHz CW-pumped regenerative amplification.
Result of diode-pumped cw laser action of Yb:GYSO are demonstrated for the first time. The laser wavelength could be tuned from 1030 to 1089 nm, and a slope efficiency of 57% was achieved.
A diode pumped cw laser operation based on 5-at.% doped Yb:GSO crystal was reported. The optical conversion efficiency of 64.5% at 1089 nm was achieved and the tuning range extends to ~65 nm.
