  • Power multi-wavelength ND: YAG laser

Special design of two- elementary single- tube laser head permitted to decrease losses significantly, related to super fluorescence and to ensure efficient work of laser in generator-amplifier operation with using only one power module and one autonomous cooling system with heat exchanger "water-to-air." The microprocessor controller provides pulse-repetition frequency manipulation, pulse delay of gate start, pumping energy and also carrying out of diagnostic laser parameters, including definition of basic frequency radiation energy, the total number of lamp flashes, statistical parameters of generation. This model was elaborated specifically for pumping of high-power tunable converters with the second harmonic radiation energy more than 400 mJ.
