title = "Comparison optical parametric oscillators based on PPKTA and PPKTP for gas analyzes",
abstract = "The optical parametric oscillator based on the first PPKTP crystal produced in Russia was created. This crystal has dimensions of 8×0.5×10 mm and polling period of Λ1=37.9 μm, Λ2=38.7 μm. The conversion efficiency of pump into idler at repetition rate 1 kHz is 7.5%, quantum efficiency 17.8% and slope efficiency 16.3%. The generation threshold was 110 μJ. The optical parametric oscillator based on the first PPKTA crystal was developed. Threshold for parametric generation was 130 μJ (14.4 MW/cm2), the quantum efficiency was 27% and the differential efficiency was 12%. The signal wavelength was 1.54 µm, and the idler wavelength corresponded to 3.31 µm.",
