Abstract
We demonstrated a repetition-rate-tunable self-mode-locked optically pumped semiconductor disk laser (OP-SDL). The highest repetition rate of mode-locked pulses was 6.13 GHz. When using an output mirror with a radius of curvature of 300 mm, the tuning range was from 0.6 GHz to 4.35 GHz. When replaced by an output mirror with a radius of curvature of 50 mm, the tuning range was from 3.13 GHz to 6.13 GHz. The entire tuning process was continuous, and OP-SDL was always in a stable mode-locked working state. To the best of our knowledge, this is the first work to obtain repetition rate of 6.13 GHz and tunable laser in self-mode-locked OP-SDLs. 3.75 GHz was the maximum tuning range of repetition rate at present.
