Abstract:
1. Laser amplifier system comprising: a solid-state body thermally coupled to a cooling member and having a laser-active volume area, at least one laser-active quantum structure consisting of semiconductor material being arranged in said laser-active volume area in at least one surface and extending at least over partial areas of said surface, a pumping radiation source adapted to generate a pumping radiation field for the optical pumping of the laser-active volume area, and an optical means of the amplifier defining a laser amplifier radiation field passing through the laser-active volume area, wherein: said laser-active quantum structure consists of one of: said pumping radiation source has a configuration and wavelength adapted to cause the direct absorption of pumping radiation from the pumping radiation field in the laser-active quantum structure to be equal to or greater than the absorption of pumping radiation by a surrounding structure adjacent to the laser-active quantum structure, and the pumping radiation field proceeds such that it passes through the laser-active quantum structure several times.
