PROCESS FOR REDUCING HIGH-FREQUENCY ENERGY NOISE COMPONENTS IN THE OUTPUT RADIATION OF A LASER, PROCESS FOR GENERATING SHORT LASER PULSES, AND LASERS UTILIZED FOR THIS PURPOSE

摘要

A laser output radiation with reduced energy noise components is produced which is also usable for the formation of short, stable laser pulses in the pico- and sub-picosecond ranges. The low noise components are obtained by superposition of the resonator wave in the active medium with its fed back output radiation lying on the order of magnitude of the spontaneous radiation emission of the oscillating resonator wave.
