Solid State Saturable Absorbers for Q-switching at 1 and 1.3 um: Investigation and Modeling

Popis výsledku v původním jazyce

Yttrium and Lutecium garnets doped by Chromium or Vanadium ions were investigated as saturable absorbers potentially useful for passive Q-switching at wavelengths 1 um and/or 1.3 um. For comparison color center saturable absorbers LiF:F2+ and Cobalt doped spinel (Co:MALO) were also studied. Firstly, low power absorption spectra were recorded for all samples. Next, absorbers transmission in dependence on incident energy/power density was measured using a z-scan method. Crystals Cr:YAG, Cr:LuAG, V:YAG, and LiF:F2+ were tested at wavelength 1064 nm. Q-switched Alexandrite pumped Nd:YAG laser was used as a radiation source. Crystals V:YAG, V:LuAG, and Co:MALO were tested at wavelength 1338 nm. Diode pumped Nd:YAG/V:YAG microchip laser was used as a radiation source . Using measured data fitting and by their comparison with numerical model of a thick saturable absorber transmission for Q-switched gaussian laser beam parameters were estimated.
