High-power 2.04 μm laser in an ultra-compact Ho-doped lead germanate fiber
PW Kuan, X Fan, X Li, D Li, K Li, L Zhang, C Yu, L Hu – Optics Letters, 2016 A highly Ho-doped single-mode lead germanate glass fiber is developed for compact ∼2 μm lasers. Over 600 mW of laser output operating at 2.04 μm is demonstrated in a 2 cm-long active...Cryogenic Ho:CaF2 laser pumped by Tm:fiber laser
M Jelínek, V Kubeček, W Ma, B Zhao, D Jiang, L Su – Laser Physics Letters, 2016 The laser operation in the pulsed as well as continuous-wave regime of a modified-Bridgeman-grown 0.5 at.% Ho:CaF2 crystal at 83 K pumped by a Tm:fiber laser is reported. The maximum...Characterization of holmium fibers with various concentrations for fiber laser applications around 2.1 μm
J Aubrecht, P Peterka, P Honzatko, Y Baravets… – SPIE Photonics Europe, 2016 In this work, we present experimental results of characterization of the developed holmium-doped silica-based optical fibers with holmium ions concentrations in the range from 1000 to...Effect of cryogenic temperature on spectroscopic and laser properties of Er, La: SrF2-CaF2 crystal
R Švejkar, J Šulc, M Němec, H Jelínková… – SPIE LASE, 2016 The laser and spectroscopic properties of crystal Er,La:SrF2-CaF2 at temperature range 80 – 300 K, which is appropriate for generation of radiation around 2.7 um is presented. The sample of...Microchip laser based on Yb: YAG/V: YAG monolith crysta
K Nejezchleb, J Šulc, H Jelínková, V Škoda – SPIE LASE, 2016 V:YAG crystal was investigated as a passive Q-switch of longitudinally diode-pumped microchip laser, emitting radiation at wavelength 1030.5 nm. This laser was based on diffusion bonded monolith...
