Abstract
Abstract Hybrid laser structures are disclosed, the structures being axial gradient lasers that are combinations of a plurality of solid-state lasable plate elements spaced along the optical axis of the laser structure and a cooling liquid that lases at the same wavelength as that of the solid-state plate elements so as to provide a high-gain, high-energy-storing laser. The solidstate plate elements can be made of a glass host material doped with trivalent neodymium, and the cooling liquid whose stimulated emission is also at a wavelength of about 1.06 microns; for example, selenium oxychloride doped with Nd3 .
