The utility model provides a two dimension reputation Q switching regulator device, the device be used for realizing that two -dimentional acousto -optic Q -switching is at the infinitely variable control of every single move with two degrees of freedom of deflecting. The utility model discloses it deflects to set up above unable adjustment base adjusts the base, and the regulation base edge that deflects has meticulous gear structure, can realize the regulation to acousto -optic Q -switching horizontal deflection under the effect of deflection adjusting gear. Deflection sets up support piece and fixes on adjusting the base. The support piece top sets up a Q -switch supporting bench, and a Q -switch supporting bench adjusts the regulation that can realize the every single move direction under the vice effect at the luffing gear to available fixing bolt is fixed. A Q -switch supporting bench top direct mount acousto -optic Q -switching. This device simple structure, it is convenient to adjust, and reputation that can the make full use of acousto -optic Q -switching is high -quality.
