description: This work is devoted to the investigation and selection of the operating modes of the laser diode seed to achieve a wide range of pulse duration and frequency of their repetition. Tasks that were solved during the study: investigation of the parameters of pulses formed in the quasi-continuous-wave operation; investigation of the parameters of pulses formed in the gain-switched laser diode; investigation of the parameters of pulses formed by a semiconductor optical amplifier; investigation of the parameters of pulses formed in the gain-switched laser diode with radio frequency excitation. A distributed feedback semiconductor laser with a radiation wavelength of 1064 nm was studied. Four schemes of optical pulse generation are proposed: nanosecond, subnanosecond, picosecond, and RF picosecond. The oscilloscope was used to measure the form of the pulses, their duration, jitter, and peak power to study the pulse parameters. As a result of the performed research, the modes of generation optical pulses with a duration from 50 picoseconds to 10 nanoseconds and with a pulse repetition frequency from 100 kilohertz to 4 gigahertz were developed.
