title = "Diamond Raman laser in eye safe region",
abstract = "The goal of this work was the external cavity CVD diamond Raman laser generating at wavelength of 1.63 uμm which belongs to an eye safe region. As the Raman medium a sample of CVD grown single diamond crystal was used. The crystal was grown in the [100] direction and after cutting, the sample sides were formed by {110} planes. The diamond crystal sample dimensions were 5 mm × 5 mm × 2 mm and it had no anti-reflection coatings. As a pumping radiation source the compact Q-switched Nd:YAP laser operating at the wavelength 1.34 uμm was used. The pulse duration was 12 ns. This pumping radiation was focused by the lens (f = 250 mm) perpendicularly on the diamond crystal face. The beam radius inside the crystal was 180 uμm. The 15 mm long Raman laser resonator was formed by a pumping mirror (HR @ 1.63 uμm and T = 97 % @ 1.34 uμm) and an output coupler (R = 95 % @ 1.63 uμm, r = 500 mm). The maximum generated laser output energy was 18 uμJ @ 1.63 uμm for the pumping energy of 3.35 μJ corresponding to the conversion efficiency of 0.5 %. The output spatial beam profile corresponds to the fundamental Gaussian beam in both axes.",
