Abstract: | Two new methods for phase-locking are used in the axisymmetrical-fold combination CO2 laser. We demonstrate the feasibility of two methods by theoretical deduction, and give the light intensity distribution of far field by numerical simulation. When phase is locked, the axisymmetrical-fold combination CO2 laser can provide a high output power with good beam quality. Furthermore, the peak light intensity of output beam with phase-locking is obviously higher than that without phase-locking. |
