DEVICE FOR HIGH-FREQUENCY EXCITATION OF GAS LASER Russian patent published in 1998 - IPC

FIELD: quantum electronics, in particular, laser systems for processing, navigation and ecological applications. SUBSTANCE: pumping oscillator is supplied with unit for generation of high-frequency pumping pulses with frequency modulation. Dispersion delay line is inserted between oscillator and excitation line. Oscillations spreading speed in said delay line depends on frequency which is matched to dependency of frequency on time during high-frequency pumping pulse. Excitation line is designed as piece of zero-dispersion waveguide. EFFECT: increased output pulse power, increased tuning range of frequency (wavelength). 3 dwg
