We demonstrate a very simple and impactful scheme based on parallel electrical relay control of conventional diodes without wavelength locking for the resonant pumping of high power fiber lasers. This scheme enhances the efficiency and reduces the thermal load on the laser. The deleterious effects due to drift in emission wavelength of the diodes from the peak absorption of the gain medium with varying output power is avoided. We also demonstrate that the proposed technique performs comparably with pumping with wavelength locked laser diodes. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement.
