High-energy picosecond pulses with a single spatial mode from a passively mode-locked, broad-area semiconductor laser
Mallachi-Elia Meller, Leon Bello, Idan Parshani +2
We present a mode-locked semiconductor laser oscillator that emits few picosecond pulses (5-8ps at 379MHz repetition) with record peak power (112W) and pulse energy (0.5nJ) directl…

Soft aperture spatial filtering: 1.5W in a single spatial mode from a highly multi-mode laser diode in an external cavity
Mallachi-Elia Meller, Idan Parshani, Leon Bello +3
Broad area laser diodes are attractive for the high optical power they can produce. Unfortunately, this high power normally comes at the cost of severely reduced spatial coherence…
