Název v původním jazyce

Tunability of Yb:glass Laser

Popis výsledku v původním jazyce

Ytterbium doped phosphate glass (5 mol% of Yb2O3, thickness 1 and 2 mm, uncoated), developed for fibre laser, was tested in bulk form as a laser active medium. For Yb:glass pumping a fibre coupled (fibre core diameter 100 ?m, NA = 0.22) laser diode withemission at wavelength 975nm was used. The laser diode was operating in pulsed regime (pulse length 1.5 ms, repetition rate 5 Hz, maximum pulse energy 22 mJ) with low duty cycle to reduce a heat accumulation inside the active medium (Yb:glass was only air-cooled). Longitudinally pumped Yb:glass samples were placed inside the 145mm long semi-hemispherical resonator formed by a flat pumping mirror (HR @ 1.0 - 1.1 ?m, HT @ 0.97 ?m) and by curved output coupler (r = 150 mm). Set of output couplers with reflectivity 91 ? 97% @ 1.0 - 1.1 ?m was used. Tuning of the Yb:glass laser was accomplished by using a birefringent filter (single 1.5mm thick quartz plate) placed inside the optical resonator at the Brewster angle between the output coupler
