Diode Pumped Tunable Lasers Based on Tm:CaF2 and Tm:Ho:CaF2 Ceramics

Popis výsledku v původním jazyce

The Tm:CaF2 (4% of TmF3) and Tm:Ho:CaF2 (2% of TmF3, 0.3% of HoF3) ceramics, prepared using hot pressing, and hot formation technique had been used as an active medium of diode pumped mid-infrared tunable laser. A fibre (core diameter 400 ?m, NA = 0.22)coupled laser diode (LIMO, HLU30F400-790) was used to longitudinal pumping. The laser diode was operating in the pulsed regime (6 ms pulse length, 10 Hz repetition rate). The duty-cycle 6% ensures a low thermal load even under the maximum diode pumping power amplitude 25W (ceramics samples were only air-cooled). The laser diode emission wavelength was 786 nm. The 80mm long semi-hemispherical laser resonator consisted of a flat pumping mirror (HR @ 1.85 - 2.15 ?m, HT @ 0.78 ?m) and a curved (r = 150mm) output coupler with a reflectivity of ~ 98% @ 1.85 - 2.0 ?m for Tm:CaF2 laser or ~ 99.5% @ 2.0 - 2.15 ?m for Ho:Tm:CaF2. Tuning of the laser was accomplished by using a birefringent filter (single 1.5mm thick quartz plate) placed inside th
