Abstract

A picosecond regenerative amplifier with pulse on demand operation is demonstrated. The pulse energy is held constant for arbitrary pulse separation by employing an intracavity loss modulator. The loss modulator is controlled by a digital signal processor monitoring the gain of the laser material in real time. The gain is estimated from a measurement of the emitted fluorescence from the upper laser level, and the signal processor adjusts the loss in such way to keep the total round-trip gain constant regardless of the time separation to the previous pulse. The system is able to completely suppress the usual multistable regimes of a regenerative amplifier operated under a variation of the repetition rate. We achieve constant output energy for a linear change of repetition rates between 0 and 100kHz with a slope of 2MHz/s.
