    Schematic setup of the V-shaped folded intra-cavity Nd:YVO4/diamond eye-safe Raman laser. M1, input mirror; M2, folding mirror; M3, dichroic mirror; M4, output coupler; AOS, acousto-optic Q-switch.
    (a) The fundamental laser beam radius distribution in the cavity. (b) The fundamental laser beam radius on both the Nd:YVO4 and the diamond under different thermal lens focal lengths.
    (a) Power transfer characteristic for the fundamental laser at 50 kHz. (b) The fundamental laser emission spectrum at 27.2 W incident pump power. Inset: a single pulse shape.
    Characteristics of the second-Stokes laser. (a) Average output power and pulse energy versus incident pump power at 50 kHz. (b) Emission spectrum for 27.2 W incident pump power. Inset: high-resolution spectrum.
    Characteristics of the second-Stokes laser. (a) Pulse width and peak power versus incident pump power at 50 kHz. (b) Average output power and peak power versus different PRFs.
    Pulse characteristics of the second-Stokes laser at 27.2 W and 50 kHz. (a) Pulse train and (b) single pulse shape.
