Abstract: A compact gain-switched all-fiber ytterbium laser operating at a wavelength of 1127 nm with the ability to control pulsed radiation parameters has been investigated. Gain switching was carried out by modulating the current of a semiconductor pump diode. With pumping energy ranging from 197.6 to 263.5 μJ, there was one generation pulse per each pump pulse with a duration of 0.43 to 1.1 μs, energy of 5.3 to 8.8 μJ, and a repetition rate of 100 Hz. Increasing the pumping energy above 265 μJ led to a change in the shape of generated pulses and to their energy rising up to 70 μJ.

Keywords: fiber laser, ytterbium laser, gain switching, pulsed radiation, fiber Bragg grating.
