In a laser, a solid luminescent sensitive element of Fabrey-Perot optical regenerative configuration and consisting essentially of a clear glass activated with trivalent ytterbium ions.
A laserable glassy material comprising a host material containing a quantity of a fluorescent ingredient which, in relation to the prevailing laser emissive light absorptive characterisitics of said host material, supports in said host material a sufficient inversion in population between two energy levels of said fluorescent ingredient as to provide, at the wavelength of stimulated emission of said fluorescent ingredient, light energy by stimulated emission in excess of all light energy losses in said laserable glassy material.
A laser component having a structure providing a wave propagation path, all surfaces of said component in said wave propagation path having total scattering of sufficiently low value to permit light energy by stimulated emission in excess of all light energy losses and at least a portion of a surface of said structure in said propagation path being at least partially transmissive of laser emissive light, said component comprising a glassy host material containing a quantity of a fluorescent ingredient which, in relation to the prevailing laser emissive light absorptive characteristics of said host material, supports in said host material a sufficient inversion in population between two energy levels of said fluorescent ingredient as to provide, at the wavelength of stimulated emission of said fluorescent ingredient, light energy by stimulated emission in excess of all light energy losses in said component.
A laser device comprising a laser component having a structure providing a wave propagation path, all surfaces of said component in said wave propagation path having total scattering of sufficiently low value to permit light energy by stimulated emission in excess of all light energy losses and at least a portion of a surface of said structure in said propagation path being at least partially transmissive of laser emissive light, said component comprising a glassy host material containing a quantity of a fluorescent ingredient which, in relation to the prevailing laser emissive light absorptive characteristics of said host material, supports in said host material a sufficient inversion in population between two energy levels of said fluorescent ingredient as to provide, at the wavelength of stimulated emission of said fluorescent ingredient, light energy by stimulated emission in excess of all light energy losses in said device, and a source of pumping energy directed into said component for establishing said population inversion.
