Abstract

Refractory oxide crystals having high-quantum efficiency and high thermal stability for use as broadly tunable laser host materials. The crystals are formed by removing hydrogen from a single crystal of the oxide material to a level below about 10.sup.12 protons per cm.sup.3 and subsequently thermochemically reducing the oxygen content of the crystal to form sufficient oxygen anion vacancies so that short-lived F.sup.+ luminescence is produced when the crystal is optically excited.

Refractory oxide hosts for a high power, broadly tunable laser with high quantum efficiency and method of making same

Patent Chen, Y; Gonzalez, R

A high power laser host material is described which is formed of a refractory oxide crystal characterized by high quantum efficiency and high thermal stability with a substantially complete depletion of hydrogen and containing sufficient oxygen anion vacancies to produce only F/sup +/ luminescence when optically excited.

Refractory oxide crystals having high-quantum efficiency and high thermal stability for use as broadly tunable laser host materials. The crystals are formed by removing hydrogen from a single crystal of the oxide material to a level below about 10/sup 12/ protons per cm/sup 3/ and subsequently thermochemically reducing the oxygen content of the crystal to form sufficient oxygen anion vacancies so that short-lived F/sup +/ luminescence is produced when the crystal is optically excited.
Stimulated Brillouin scattering mirror system, high power laser and laser peening method and system using same

Patent Dane, C Brent [Livermore, CA]; Hackel, Lloyd [Livermore, CA]; Harris, Fritz B [Rocklin, CA]

A laser system, such as a master oscillator/power amplifier system, comprises a gain medium and a stimulated Brillouin scattering SBS mirror system. The SBS mirror system includes an in situ filtered SBS medium that comprises a compound having a small negative non-linear index of refraction, such as a perfluoro compound. An SBS relay telescope having a telescope focal point includes a baffle at the telescope focal point which blocks off angle beams. A beam splitter is placed between the SBS mirror system and the SBS relay telescope, directing a fraction of the beam to an alternate beam path for anmore »« less

Target isolation system, high power laser and laser peening method and system using same

Patent Dane, C Brent [Livermore, CA]; Hackel, Lloyd A [Livermore, CA]; Harris, Fritz [Rocklin, CA]

A system for applying a laser beam to work pieces, includes a laser system producing a high power output beam. Target delivery optics are arranged to deliver the output beam to a target work piece. A relay telescope having a telescope focal point is placed in the beam path between the laser system and the target delivery optics. The relay telescope relays an image between an image location near the output of the laser system and an image location near the target delivery optics. A baffle is placed at the telescope focal point between the target delivery optics and themore »« less

Tunable photoluminescent metal-organic-frameworks and method of making the same

Patent Nenoff, Tina M.; Sava Gallis, Dorina Florentina; Rohwer, Lauren E.S.

The present disclosure is directed to new photoluminescent metal-organic frameworks (MOFs). The newly developed MOFs include either non rare earth element (REE) transition metal atoms or limited concentrations of REE atoms, including: Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Y, Ru, Ag, Cd, Sn, Sb, Ir, Pb, Bi, that are located in the MOF framework in site isolated locations, and have emission colors ranging from white to red, depending on the metal concentration levels and/or choice of ligand.
