Paper Abstract
The paper presents a current state of the project aiming to develop a compact and mobile pulsed laser source, operated in
“eye-safe” spectral region (1.5 μm). It will be a high power, all-fiber system generating nanosecond pulses with
repetition rate ranging from tens to hundreds kHz and built in Master Oscillator Power Amplifier (MOPA) configuration.
First amplifying cascade of the system has been developed. Distributed Feedback (DFB) laser diode with home-built
supply and pulse control system was used as a master oscillator. It can generate rectangular laser pulses with
independently changeable repetition rate (10 – 200 kHz) and pulse width (20 – 300 ns). The system provides over 34 dB
optical gain. In addition, simulations of amplification laser radiation in the active fiber for different input pulse energies
in relation to saturation energy were presented. Furthermore theoretical and experimental optimization of an active fiber
length was done. In the first elaborated stage of amplifier 18,1 % slope efficiency was obtained.
