26.6 μJ microsecond tunable burst-mode pulsed laser based on synchronous pumping

We have demonstrated a 26.6 μJ microsecond GHz tunable burst-mode pulsed laser. The burst-mode laser has a pulse duration of 5.5 μs, and the repetition rate of the intra-burst can be adjusted from 1 to 2 GHz. To mitigate amplified spontaneous emission and non-linear effects, we have implemented a synchronous pumping scheme in the secondary pre-amplifier, and achieved a maximum energy output of 26.6 µJ. Furthermore, the envelope of the burst-mode pulsed laser is maintained with uniformity through a pre-compensation acoustic-optical modulator.
