CW mode-locked self-Raman 1.17 μm Nd: GdVO4 laser with a novel long cavity

• The stable CW mode-locked pulse in a diode-pumped self-Raman 1.17 μm Nd:GdVO4 laser was achieved.
• A novel design of cavity included a special dichroic mirror could decrease the mirror loss and increase the slope efficiency.
• Q-switched mode-locked and stable CW mode-locked at different incident pump power were observed.
• With an incident pump power of 10 W, the average output powers was up to 103 mW at a repetition rate of 145 MHz.

In this paper we report on a mode-locked self-Raman 1.17 μm Nd:GdVO4 laser. We successfully achieved stable CW mode-locked pulse in a diode-pumped self-Raman Nd:GdVO4 laser with a novel design of cavity included a dichroic mirror used in a special way. With an incident pump power of 10 W, the average output powers was up to 103 mW at a repetition rate of 145 MHz.
