Abstract

We investigate an external cavity curved two-section mode-locked diode laser system based on quantum-dot (QD) gain media near 1.3 mu m. Pulses are generated from the external laser cavity at a 5-GHz repetition rate and amplified using a multilayer quantum-dot semiconductor optical amplifier. The pulses are compressed with a dual-grating dispersion compensator. The shortest, near transform-limited pulses are obtained when the mode-locked pulses are positive (up) chirped. The compressed pulses are 1.2 ps in duration, with a pulse energy of 1.46 pJ, implying a peak power of 1.22 W. (c) 2005 American Institute of Physics.
