Coupled CO2 lasers

This paper reviews experimental results obtained during research on the possibility of developing high power laser systems based on coupled CO2 laser arrays. Resonator mirrors were used for individual laser coupling and the Talbot effect and spatial filters were used for phase locking of laser arrays. New methods of phase locking of individual lasers are discussed. Far-field intensity distributions of coupled CO2 lasers and laser arrays are presented. The aperture filling method of main lobe energy maintenance increase is described and generation stability of coupled lasers is considered. The realization of a coherent energy regime of individual lasers in array is a possible method of improving radiation divergence and developing high power and compact CO2 lasers for industrial applications

Generation and control of intense laser beams in multibeam laser systems

The modern state and perspectives of development of high power multibeam CO2 lasers are described. The problems of phase locking of laser arrays and main lobe energy maintenance increase are discussed also.

Modern multibeam CO2 lasers and perspectives of their development

The results of experimental and theoretical investigations of the different methods of phase locking of an array of lasers, the selection one supermode and the increasing of energy in mane maximum of focal spot are described. The practical realization of this methods opens the real perspectives to improve the brightness of radiation of multibeain CO2 lasers and to expand the area of there application in the thermal technology.
