Abstract
We demonstrated sub-nanosecond pulse width at single longitudinal mode operation in a diode-pumped electro-optically Q-switched Nd:YVO4 laser. The laser used one reflecting Bragg gratings (RBG) as output coupler for mode selection. Stable, single-mode longitudinal operation with laser pulse of 0.43mJ energy, peak power of 0.66MW and duration of 645ps at 5 to 150Hz was realized from a 38mm long optical resonator.
