Dependences of the contrast ratio on the angular deviation of the optical axis with a step of 2 arcmin 28 arcsec have been obtained for Pockels cells based on beta barium borate crystals in the 49 arcmin 34 arcsec range. The investigation was conducted for a single Pockels cell and for a double cell based on optically aligned crystals. The results of investigations can be applied for the calculation of the laser beam focus in order to use a high contrast ratio in high-power laser systems when the light is modulated using Q-switching.

A Gw-level high-power CO2 laser system has been developed. A short laser pulse is cut out with a double Pockels cell electrooptical shutter from a hybrid CO2 laser oscillator and amplified with a three-stage dual-path TEA preamplifier, a two-stage TEA preamplifier, a large aperture TEA amplifier, and an electron beam-controlled final amplifier. All parts of the laser system are controlled with a control system. The laser output power is up to 3.2 × 109 W and laser pulse width is 4 ns full width at half maximum.
