Mode-locking of the disordered cubic sesquioxide crystal Yb:LuScO3 using a reflection-type single-walled carbon nanotube saturable absorber is demonstrated under diode pumping and compared with passive mode-locking by a commercial SESAM.
CW laser operation of Tm3+ in Czochralski-grown disordered NaY(WO4)2 crystals is demonstrated. The tunability extends from 1847 to 2069 nm. The maximum slope efficiency and output power amount to ap43% and ap400 mW, respectively.
Q-switched diode-pumped Yb:YAl3(BO3)4 lasers provide an average output power of 4.15 W, pulse energy of 139 muJ, pulse duration of 18 ns, and a slope efficiency of 59% operating near 1040 nm at room temperature.
Single-walled carbon nanotube saturable absorbers were designed for passive mode-locking near 1 mum. Using Yb:KYW and Yb:KLuW, nearly transform-limited sub-150 fs pulses were generated at 1037 nm and 1048 nm, respectively.
We report the shortest pulses (62 fs) ever produced with an Yb-doped monoclinic double tungstate laser by passive mode-locking of diffusion-bonded Yb:KY(WO4)2/KY(WO4)2 achieving an average power of 182 mW at 1029 nm.
Single-pass pumping of a thin disk consisting of a 50 mum epitaxial layer of 32% Yb-doped KLu(WO4)2 deposited on a KLu(WO4)2 substrate produced 9 W of output power near 1030 nm at 77% slope efficiency.
Output power of 470 mW, slope efficiency of 64.5% and tunability between 1016 and 1049 nm are achieved with the novel disordered uniaxial crystal Yb:LiGd(MoO4)2. Both possible polarizations are compared and diode-pumping is also demonstrated.
Maximum output powers of 1.4 and 4 W and slope efficiencies of 60 and 69% were obtained with a Tm:KLu(WO4)2 laser near 2 mum under Ti:sapphire and diode laser pumping, respectively.
We demonstrate output powers exceeding 4 W with continuous-wave, diode-pumped Yb:TVO4 (T=Y, Gd, and Lu) lasers operated at room temperature. The three orthovanadate hosts are compared in longitudinal and thin-disk pump geometries.
