Four Micron Radiation Generated by Dysprosium Doped Lead Thiogallate Laser

Popis výsledku v původním jazyce

The lead thiogallate (PbGa2S4) crystal doped with trivalent dysprosium ions was used as a laser active medium for obtaining radiation in mid-IR spectral region. To prove in-band pumping, the Er:YAP laser generating 1.66 um radiation was used. The Dy:PbGa2S4 laser was working at room temperature without any cooling. Three Dy:PbGa2S4 active crystals were investigated. The maximal reached output energy was as high as 275 uJ for the optimal mirror reflectance and the best Dy:PbGa2S4 crystal. The incident pumping energy was 132 mJ. The measured output radiation wavelength was 4332 nm with the spectral width of 62 nm. From the point of efficiency it was recognized that the in-band pumping directly into 6H11/2 level results in decrease of lasing threshold andincrease of slope efficiency.
