LASER SYSTEM AND DOUBLE-PULSE LASER Russian patent published in 2000 - IPC

FIELD: quantum electronics. SUBSTANCE: laser system designed for use as radiator in lidar systems, spectroscopy of liquids, gases, and solids, as well as in double-pulse holographic interferometry has laser adjustable within broad band of wavelengths, pulsed laser for optical pumping of adjustable laser active material, optical system for pumping radiation input. Pulsed pumping laser emits two pulse radiation beams spatially separated in and arranged strictly in parallel. Time space between pulses is controlled. Generated pair of radiation pulses has line width smaller than . EFFECT: improved precision of beam length adjustment, facilitated readjustment of pulse-to-pulse spectral gap. 2 cl, 2 dwg
