A transversely pumped Nd:YAG laser with a pulse energy of \u223c4 mJ and a spatial beam distribution described by a second-order Gaussian function along the <i>x<\/i> axis and a fourth-order Gaussian function along the <i>y<\/i> axis is used as a pump source. A maximum achievable radiation energy of the optical parametric oscillator is at a level of 360 \u03bcJ for a wavelength of 3.3 \u03bcm, 130 \u03bcJ for a wavelength of 4.73 \u03bcm, and 110 \u03bcJ for a wavelength of 7.40 \u03bcm. The developed radiation source is used to record absorption spectra of gas mixtures of methane, propane and nitrogen dioxide.<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> <i>optical parametric oscillator, nonlinear crystal, pulsed pump laser, laser photoacoustic spectroscopy.<\/i><\/div>\n<div><\/div>\n<div>The work was supported by the Russian Science Foundation (scientific project no. 17-72-30006-P).<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 10.09.2023<br \/>\n<b>Revised:<\/b> 28.11.2023<br \/>\n<b>Accepted:<\/b> 28.11.2023<\/div>\n","protected":false},"excerpt":{"rendered":"<p>E.
