The slave amplifies the injected frequency-shifted master beam while suppressing (within 0.5  %) the strong dependence of its intensity on the acousto-optic frequency shifter carrier frequency, thus acting as a strongly saturated optical limiting amplifier with constant output power. The resulting beam is then amplified in a tapered amplifier. The system provides an output power above 700 mW at a wavelength of 780 nm, with a time-averaged linewidth of 0.6 MHz, and a frequency drift below 2 MHz/h. Dichroic atomic vapour laser lock enables frequency stabilization in the range of 400 MHz around D2 lines of rubidium. The mode-hop-free tuning range amounts to 2 GHz. Determined by the acousto-optic frequency shifter model used, the fine-tuning range (precision of few tens kHz) spans 70 MHz. A description of the system was presented and its performance was tested. The basic components have been designed in our laboratory.}, type={Article}, title={Simple three-stage frequency-stabilized diode laser system using injection-locking and tapered amplifier}, URL={http://journals.pan.pl/Content/122504/PDF-MASTER/OPELRE_2022_30_1_J_Szonert.pdf}, doi={10.24425/opelre.2022.140146}, keywords={diode laser, optical injection-locking, master oscillator power amplifier, optical limiting amplifier, tapered amplifier}, }
