Abstract :
Laser processing of pyrographite was carried out on different technological setups by radiation of the solid-state laser with wavelength X= 1.064 mum and pulse duration tau = 4middot10-3 s, tau = 1.5middot10-4 s, tau = 1.2middot10 -7 s. The power density of falling radiation was changed in a range 106-107 W/cm2. Residual temperature stresses were studied by the X-ray method. Minimization of residual temperature stresses is determined
