Patent number: 11476630Abstract: A thin film Brewster coupling device configured for low loss transmission of an imposed polarized parallel to plane of incidence 8.5 micron to 11.5 micron wavelength laser beam and simultaneous high reflectivity of a polarized perpendicular to plane of incidence 2 micron to 4 micron wavelength laser beam. The device comprising an optical media substrate and at least one dielectric stack optically coupled to the optical media substrate where the dielectric stack comprises a dielectric layer and an overlayer, the dielectric layer and the overlayer each comprising a thickness of nominally a quarter wavelength of the 2 micron to 4 micron wavelength laser beam, and oriented at near the Brewster Angle to the incident 8.5 micron to 11.5 micron wavelength laser beam. The substrate and dielectric mediums of necessary characteristics to result in low LIDT, high strength, chemical inertness and high thermal conductivity.Type: GrantFiled: June 1, 2021Date of Patent: October 18, 2022Inventor: Robert Neil Campbell

Patent number: 10797466Abstract: Efficient laser diode excited Thulium (Tm) doped solid state systems, directly matched to a combination band pump transition of Carbon Dioxide (CO2), have matured to the point that utilization of such in combination with CO2 admits effectively a laser diode pumped CO2 laser. The laser diode excited Tm solid state pump permits Continuous Wave (CW) or pulsed energy application. Appropriate optical pumping admits catalyzer free near indefinite gas lifetime courtesy of the absence of significant discharge driven dissociation and contamination. As a direct consequence of the preceding arbitrary multi isotopologue CO2, symmetric and asymmetric, gas mixes may be utilized without significant degradation or departure from initial mix specifications. This would admit, at raised pressure, a system continuously tunable from approximately 9 ?m to approximately 11.5 ?m, or sub picosecond amplification.Type: GrantFiled: September 1, 2017Date of Patent: October 6, 2020Inventor: Robert Neil Campbell

Patent number: 9059561Abstract: The closed cycle solid state optically pumped gas hybrid (chemical recovery) system utilizes a laser diode excited solid state, fiber or bulk, laser as a pump for a molecular gas, or gas mix, medium. The existence of efficient high power laser diode excited solid state fiber or bulk lasers, output spectrally matched to suitable principle and excited level 1st and 2nd overtones of relevant gases, is the enabling system technology. The utilization of such in combination with suitable gases introduces a range of viable, in principle sourcing on laser diodes and thus effectively laser diode pumped, gas laser systems with access to the approximately 4.5 ?m to approximately 5.4 ?m spectral region. Continuous wave or pulsed operation, with significant energy capability courtesy of solid state storage, is admitted.Type: GrantFiled: November 22, 2013Date of Patent: June 16, 2015Inventor: Robert Neil Campbell
