Abstract

We demonstrated a wavelength tunable mode-locked optically pumped semiconductor disk laser (OP-SDL) based on a SESAM. The wavelength tuning is achieved by incorporating an uncoated, 100 μm thick, fused silica etalon into the cavity of the laser, and the central wavelength of the pulse train varied from 972 nm to 977 nm. The average power of the mode-locked states measured at different wavelengths was about 80mW, meanwhile, the repetition rate was 1.2 GHz in the tuning process, and the signal-to-noise ratio of the radio frequency spectrum signal exceeds 50 dB, which illustrates that the laser can maintain a stable mode-locked state even the central wavelength varies greatly. In addition, we calculated the influence of etalon's related parameters on its transmittance. This research contributes to the development of wavelength-tunable mode-locked OP-SDLs and to gain practical applications in related fields.
