It is shown that the use of several laser pulses makes it possible to proportionally increase the intensity of the emitted terahertz pulses at a radiation conversion coefficient of the order of several percent. A scheme is proposed for the interference amplification of terahertz pulses in a given direction during synchronous irradiation of several identical targets.<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> terahertz radiation, femtosecond laser pulses, discharge currents.<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 30.11.2022<br \/>\n<b>Accepted:<\/b> 30.11.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>N.
