Abstract:
Laser glass compositions are disclosed that provide laser articles with increased efficiency, the compositions comprising TeO2, La2O3 and ZnO in certain molar amounts, as defined by certain areas set forth in a ternary diagram of the FIGURE, the laser glass compositions also including an effective lasing amount of Nd2O3. Also disclosed are methods of making highly efficient glass laer articles, such as rods, discs and the like, the methods including the steps of: 1. MELTING LASER GLASS BATCH-FORMING MATERIALS TO PROVIDE MOLTEN GLASS COMPRISING CERTAIN MOLAR AMOUNTS OF TeO2, La2O3 and ZnO, the molten glass capable of being a host for an effective lasing amount of Nd2O3; 2. forming a glass laser blank from the molten glass; and 3. FABRICATING A LASER ARTICLE FROM THE GLASS BLANK, THE ARTICLE HAVING INCREASED LASING EFFICIENCY. Also disclosed is the new use of a TeO2/La2O3/ZnO glass host composition as a glass laser article in which the proportions of TeO2, La2O3 and ZnO are present in certain molar amounts as above-described, and in which the glass composition is a host for an effective lasing amount of Nd2O3, the new use including the steps of: 1. FORMING A LASER ARTICLE FROM THE GLASS COMPOSITION ABOVEDESCRIBED; 2. PUMPING THE LASER ARTICLE TO CAUSE AN ENERGY INVERSION; AND 3. PASSING MONOCHROMATIC LIGHT THROUGH THE ARTICLE TO CAUSE STIMULATED EMISSION AT A WAVELENGTH OF ABOUT 1.06 MICRONS.

Abstract:
A laser assembly that includes a novel glass laser disc having an annular alkali lead borate glass coating for use in the assembly is disclosed. The annular coating has an index of refraction that is about 3 to 12 percent greater than the index of refraction of the laser disc, the thermal properties also being sufficiently matched with the glass laser disc so as to prevent the development of undesirable strains therein, the glass coating comprising a mixture of alkali metal oxides in which at least two different alkali metal oxides are present, and any K2O that is present is limited to an amount of not substantially more than about 1 percent by weight and an effective energy absorbing amount of heavy metal oxide that absorbs energy at a wavelength of about 1.06 microns to prevent parasitic oscillations. The heavy metal oxides include oxides of transition metals of the 3d, 4d, 4f, 5d and 5f orbital series.

Abstract:
A laser assembly is disclosed, the laser assembly including a crystalline laser disc, such as a ruby disc, that has an annular glass coating for absorbing energy at the lasing wavelength to thereby prevent parasitic oscillations. The preferred glass coating for a ruby laser disc is a barium oxide lead borate glass containing SiO2, ZnO and an effective energy-absorbing amount of copper oxide to prevent parasitic oscillations.
