    Investigation of Yb:LuAG Crystals with High Doping Concentration

  • Original language description

    Two Yb:LuAG (Yb:Lu3Al5O12) plates (thickness 1.05 mm, diameter 3 mm, AR/AR @ 0.9 - 1.1 ?m, Yb-doping c = 15% and 20 %) were prepared for laser experiments. For Yb:LuAG pumping, fibre coupled laser diode operating in pulsed regime was used (fibre core diameter 100 ?m, emission wavelength 968 nm, pulse length 2 ms, repetition rate 10 Hz, maximum energy 40 mJ). The longitudinally pumped Yb:LuAG was placed inside the 148mm long resonator formed by a flat pumping mirror (HR @ 1.0 - 1.1 ?m, HT @ 0.97 ?m) andby a curved output coupler (radius of curvature 150 mm). Set of output couplers with reflectivity R = 70 - 97% @ 1.0-1.1 ?m was used and the output power amplitude was measured in dependence on absorbed pumping power amplitude. It was found that for bothsamples the output coupler reflectivity had only minor influence on laser output parameters expect emission wavelength (1048nm for R < 90% and otherwise 1031 nm). The sample with lower concentration had a lower threshold (~ 2.5W for c =
