FIELD: electricity.SUBSTANCE: invention is related to the area of laser-pumped light sources. The focused laser beam (7) is directed to the emitting plasma area (5) bottom-up: from the lower wall (10) of the chamber (1) to the opposite upper wall (11) of the chamber (1), and the emitting plasma area (5) is placed close to the upper wall (11) of the chamber (1). In the invention embodiments the focused laser beam is directed along the vertical axis (13) the chamber walls (10, 11) symmetry, the emitting plasma area (5) is generated at optimal small distance from the upper wall (11) of the chamfer (1), which does not impact negatively the device resource; the chamber (1) is cooled by the protective gas flow (40) directed to the upper wall (11) of the chamber (1) and by means of the automated control system (46, 47, 49) the preset emitting power is maintained in preprogrammed mode.EFFECT: expanding functionality of the laser-pumped light source due to improvement of its spatial and energetic stability, increasing brightness and operational reliability in long-term mode at that providing compact sizes of the device.26 cl, 1 tbl, 5 dwg |
