This paper describes the theory, structure and technology of the laser carving machine. The method of two-rods bonding double-pumped in the same cavity used is used to get high power laser. The deflection of the oscillation is controlled by computer software. Basing on the property of the carved materials, we must use the software to adjust the laser pulse width and repeated frequency. The nonlinear effect can be rectified by software. On the two carving methods, the scanning method is suitable for carving image, while the method of vector graph is suitable for carving graph, because the oscillation has the property of speedy positioning.
