Paper Abstract

The questions of optical beam quality of COIL are considered. The classification and meanings of different type of optical aberrations in COIL is presented. The ways of compensation of amplitude aberration by structure-parametrical optimization of the unstable resonator are offered. The scheme of automatically resonator alignment for compensation of phase aberrations originated from misalignment is presented. The 3D numerical modeling and investigation of gas flow and chemical kinetic in COIL is fulfilled. The scales and magnitude phase aberrations coimected with gas flow non-homogeneities are analyzed. The optimization of the COIL nozzle bank length from point of view of maximal beam brightness is fulfilled.
