Abstract

An unstable resonator having high magnification and capable of accommodating an active medium having high gain and small dimensions is disclosed. The unstable resonator, formed with a pair of coupled cavities, has a diffraction grating capable of providing high resolution of the bandwidth of radiation from a high gain medium such as a dye medium and is capable of providing a laser beam with a continuous cross-section having far field characteristics of high quality.
