description: Â  Â  The topic of the graduation thesis: "Study of the amplification of nanosecond pulses generated by semiconductor laser diodes in fiber and semiconductor optical amplifiers." Â  Â  The work is devoted to the study of the amplification of nanosecond pulses generated using a semiconductor diode with distributed feedback. The purpose of this work is to study the possibilities of amplifying nanosecond pulses generated by semiconductor laser diodes using fiber and semiconductor optical amplifiers. Â  Â  The object of research is the master oscillator and power amplifier. In the present study, the temperature of the driver laser diode was 32 ÌC to provide an emission wavelength of 1064 nm. The pulse repetition rate was 10 kHz, and the duration varied in the range of 3â 20 ns. For amplification, fiber and semiconductor amplifiers are used. The paper considers the basic principles of operation of these devices, as well as experiments on the amplification of nanosecond pulses. To study the radiation parameters, an oscilloscope was used to measure the pulse shape, a spectrometer, and a power meter. Â  Â  As a result of the research, it was shown that the use of a semiconductor optical amplifier as the first amplification stage does not give the required result. At the same time, the use of fiber amplifiers in both stages makes it possible to obtain the required power, spectral, and temporal characteristics of optical pulse.
