Název v původním jazyce

Tm, Ho:GGAG crystal for 2.1 μm tunable diode-pumped laser

Popis výsledku v původním jazyce

The spectroscopy properties and wavelength tunability of diode pumped laser based on Tm, Ho:GGAG single crystal were investigated. A fiber coupled laser diode was used for longitudinal pumping of Tm, Ho:GGAG. The laser diode was operating in the pulsed regime (5 ms pulse length, 10 Hz repetition rate, 785 nm emission wavelength, maximum power amplitude 16.8 W). The 150 mm long hemi-spherical laser resonator consisted of a flat pumping mirror (HR @ 1.852.11 μm, HT @ 0.78 μm) and concave (r = 150 mm) output coupler with a reflectivity of ≈97% @1.8 2.10 m. Wavelength tuning was accomplished by using 1.5 mm thick SiO2 birefringent plate. For the sample with 3.97 at.% Tm, 0.38 at.% Ho concentration, the measured maximal output power amplitude was 1.04 W at 2086 nm with a slope efficiency of 23.6%. For the sample with 7.65 at.% Tm, 0.68 at .% Ho concentrations, the measured maximal output power amplitude was 2.30 W at 2090 nm with a slope efficiency of 26.5%.n
