Telescopic system for shaping laser beams with phase-compensation correction for the output section

<title>Experimental study on phase conjugation correction of distortions imposed by telescope elements</title>

“…The TENOCOM work principle was described in [3]. To apply the system for CO laser output correction the main attention was paid to the master oscillator design in the experiments, because the beam divergence of the laser at the pulse duration of dozens microsecond was drastically increased via LIMP effect in a laser medium.…”

“…The system is based on the application of so-called by-pass scheme [2] and grating made on a secondary mirror surface (the system was named TENOCOM -TElescope with Nonlinear Optical COMpensation) [3]. The system deletes restrictions on the use of a large aperture segmented primary mirror in telescopes.…”
