A multi-degree of freedom laser processing device. Compared to existing laser processing devices, the multi-degree of freedom laser processing device further comprises: a rotary motor (8) and first transmission mechanism that are provided on a base； a light guiding tube (37) that is rotatably arranged on a light guiding tube frame (1-1) which is connected to the base, wherein the light guiding tube is driven by the rotary motor (8) by means of the first transmission mechanism and is controlled to rotate on the light guiding tube frame. The device increases the degree of freedom for laser processing, and solves problems in related technology of a limited action range and of being unable to meet application requirements in which there are large ranges and multiple surgeries due to a numerical control laser automatic tooth preparation device only being able to implement three degrees of freedom.
