ABSTRACT
A self-mode-locked HoGdVO4 laser with the GHz pulse repetition frequency oscillation near 2.06â
µm was demonstrated for the first time to our knowledge. The output performances of the self-mode-locked HoGdVO4 laser were investigated for a few output coupler transmittances at the pulse repetition frequency of 1.89â
GHz. At the incident pump power of 8.12â
W, the maximum average output power was as high as 2.28â
W, corresponding to the slope efficiency and optical-to-optical efficiency of 36.3% and 28.1%, respectively. This is the maximum average output for the 2â
µm self-mode-locked solid-state laser with a GHz pulse repetition frequency. This work provides a new way for generating an efficient and a high-power ultrafast pulse laser with a GHz repetition frequency in the 2â
µm wave band.
