Optical output power as a function of the injection current of the external-cavity mode-locked LD for several different SA reverse biases. The LD used had a long gain section and long SA section.
Characteristics of the optical pulses generated from a passively mode-locked external-cavity laser under 95 mA gain-section current and 11 V SA reverse bias at 404.5 nm center-wavelength tuning. (a) rf spectrum, (b) optical spectrum, and (c) single-shot streak-camera trace.
Single-shot streak-camera traces for optical pulses obtained with three different SA reverse biases.
Optical pulse duration as a function of the SA-section reverse-bias voltage. The optical pulse duration was evaluated from 100 single-shot streak-camera traces for each SA-section reverse bias.
