200-fs optical pulse generation and intracavity pulse evolution in a hybrid mode-locked semiconductor diode-laser/amplifier system.

Optical pulses of 200 fs with 165 W of peak power have been generated from an AlGaAs semiconductor diode-laser system. These pulses represent, to our knowledge, both the shortest and most intense ever generated from an all-semiconductor injection diode-laser system. The intracavity pulse evolution in the external cavity is also investigated experimentally.

Generation of subpicosecond high-power optical pulses from a hybrid mode-locked semiconductor laser.

Ultrashort optical pulses 0.46 psec in duration with over 70 W of peak power are generated from an all-semiconductor laser-diode system. These results represent to our knowledge both the shortest and most-intense optical pulses generated from an all-semiconductor laser system.
