摘要： The field of the invention is that of high-energy laser beam amplifiers and associated optical pumping devices. The object of the invention is to use an amplifier configuration and a cooling means which do not have the drawbacks of cryogenic systems that have been used up until now and which however make it possible both to obtain an amplified laser beam of high quality and to minimize transverse lasing effects. A laser beam amplifying device according to the invention combines four main principles, which are use of a crystal exhibiting circular symmetry so as to distribute the mechanical stresses radially; cooling of the entire external surface by a cooling liquid, so as to avoid the use of cryogenic techniques; use of a matching liquid so as to avoid transverse lasing effects; and use of pump laser beams with uniform energy distribution.
