【Abstract】 Characteristics of modes selection is demonStrated by using a stable concave convex resonator in a high POwer lasers for finite Fresnel number. Large mode volumesof the fundamental mode can be achieved by operating near a limit of stability in the gdiagram,and it proved to be a effective method for modes selection with the resonator.更多还原
