Bandwidth-limited picosecond pulses from an actively mode-locked GaAlAs diode laser

Bandwidth-limited pulses (16 ps duration, \Delta t \Delta \nu = 0.36 ) are obtained from an actively mode-locked GaAlAs CW diode laser. Replacing the 380 MHz sinewave modulation by repetitive ∼300 ps pumping pulses produces more stable operation at 1 W peak power output pulses. A synchronized streak...

Summary:Bandwidth-limited pulses (16 ps duration, \Delta t \Delta \nu = 0.36 ) are obtained from an actively mode-locked GaAlAs CW diode laser. Replacing the 380 MHz sinewave modulation by repetitive ∼300 ps pumping pulses produces more stable operation at 1 W peak power output pulses. A synchronized streak camera monitors the pulse profiles and reveals that the modulation frequency must be maintained stable to <10 kHz to avoid pulse broadening and substructures.
