Research Abstract

We demonstrated an optical cavity that supports a hollow-mode laser beam. The specifications of the cavity was not enough compared with spherical mirror cavity, but the study results showed guide lines for further development. Concerning the improvement of laser-Compton process, it is not effective by the present hollow beam cavity. However, we concluded that this technique has more potential for longer wavelength (～10μm) lasers.
