An algorithm is developed for the operation of the adaptive system to determine and correct wavefront aberrations of the laser beam in the amplification path without and with pumping slabs based on neodymium phosphate glass. Characteristic thermal aberrations of the amplification path that occur under slabs pumping are presented. A possibility of compensating for thermal aberrations in the amplifier path and the formation of a laser beam with an energy of up to 25 kJ and wavefront parameters of PV \u2248 1.4 \u03bcm and RMS \u2248 0.2 \u03bcm are experimentally demonstrated.<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> <i>adaptive system, deformable mirror, wavefront sensor, aberrations, laser radiation divergence.<\/i><\/div>\n<div class=\"around-button\"><b>Received:<\/b> 21.11.2023<br \/>\n<b>Revised:<\/b> 10.01.2024<br \/>\n<b>Accepted:<\/b> 01.02.2024<\/div>\n","protected":false},"excerpt":{"rendered":"<p>S.
