Abstract :
The efficient all-fiber amplifier operating at the wavelength of 1.5 μm was developed. It generated pulses of changeable duration in the range of 1-5 ns at the repetition of 0.2-2 MHz. The linewidth of the output laser radiation was below 100 pm and the spectrum did not reveal any significant presence of amplified spontaneous emission. For 1 MHz repetition rate stable 1-ns pulses with the energy of 2.36 μJ and corresponding 2.36 kW peak-power were obtaied. For 200 kHz repetition rate 1.2-ns pulses with the energy of 4 μJ were achieved. It corresponded to 3.4 kW peak-power.
