© 2019 Kvantovaya Elektronika, Turpion Ltd and IOP Publishing Ltd.A laser source for bleaching passive Q-switches of erbium-ytterbium lasers is developed and studied. The developed and studied compact pulsed module (peak power exceeding 10 W in a pulse with a duration of 1 μs at a wavelength around 1550 nm) is made on the basis of a semiconductor lasers with an ultra-narrow waveguide integrated with a pulsed pump card. To optimise the output laser characteristics, a series resistance was used in the laser pump circuit. The powers of the free-space and fibre-coupled modules at a temperature of 25 °C are 15 and 12 W, respectively, at a pulse shape close to rectangular.
