Abstract
The mode of generation of picosecond optical pulses in the spectral range near 1064 nm by semiconductor lasers with distributed feedback and active region based on an InGaAs/GaAs quantum well has been studied. In the gain-modulation mode, the width of laser pulses decreases from 150 to 35 ps as the temperature increases from 5 to 50°C. It was demonstrated that there is a temperature range in which the pulse width is at a minimum, 35 ps, at a full spectrum width at half-maximum of 70 pm. The laser was mounted in a hermetically sealed butterfly case, which enabled a temperature tuning of the wavelength within 3 nm in the generation mode of pulses with width less than 45 ps. The peak output power was 0.4 W at the outlet of a single-mode fiber, with the polarization preserved.
