We demonstrate passive mode-locking of a Nd:Sc0.2Y0.8SiO5 laser using a semiconductor saturable absorber mirror. The pulse train shows output power of 0.5 W and pulse duration of 3.5 ps at repetition rate of 118 MHz.
Recently, diode-pumped solid-state lasers based on disordered Nd-doped crystals have attracted significant attention. In mode-locked operation they have a potential to generate tunable laser radiation with pulse duration in sub-picosecond time scale as well as to emit muti-wavelength ultrashort pulses which makes them attractive as a source for terahertz generation [1]. Nowadays, the binary and ternary...
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,...
Effective diode-pumped cw tunable laser action of a new crystal Yb3+:Lu2Si2O7 (LPS) is demonstrated for the first time to our knowledge. The advantage of Yb: LPS is the presence of effective low-symmetry monoclinic structure and its single crystallographic site, which are benefit for the low threshold and high output energy. With a 5-at% Yb: LPS sample, we achieved 2.22 W output power at 1070 nm....
Diode-pumped stable CW mode-locked laser in Yb:LuAG crystal was demonstrated. The pulse duration of 7.63 ps was achieved without any negative dispersion elements. With pump of 8 W, output power was 610 mW with repetition rate of 86 MHz.
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.
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.
