Patent number: 9293885Abstract: A continuous-wave (CW), ultraviolet triply-optically-pumped atomic laser (TOPAL) is disclosed. The inventive laser device includes a laser active media comprising a mixture of a neutral atomic vapor and one or more buffer gases. The gain mixture is placed within a segmented gain cell, allowing for periodic, selected spectral filtering of deleterious ASE transitions; the segmented gain cell, in turn, is placed within an optical cavity with a high Q at a specified ultraviolet wavelength, and is successively, resonantly excited by three drive pump lasers, in three energy-contiguous visible/IR electric-dipole allowed transitions, producing a steady-state electron population inversion density between a high-lying electronic energy level and the ground electronic level, and producing laser emission on a UV transition (within the spectral range ˜230 to ˜370 nm) terminating on the ground electronic level.Type: GrantFiled: March 6, 2014Date of Patent: March 22, 2016Inventors: William F Krupke, David Eimerl

Patent number: 8291913Abstract: Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.Type: GrantFiled: August 18, 2008Date of Patent: October 23, 2012Assignee: Reliant Technologies, Inc.Inventors: David Eimerl, Leonard C.

Publication number: 20090192885Abstract: A method is presented for increasing sales by inducing the customer to interact with a product that attracts their interest, even if that interest is minimal or transient. The method utilizes a display monitor placed close to a product that shows an informational presentation on the product, but only when activated by a customer. The presentation is activated when a customer touches the display. The monitor and activation means are placed close to the product, rather than elsewhere in the store, sufficiently close that a customer located within viewing distance and within touching distance of the product can also reach out and activate the presentation without taking a step. The display is placed at a convenient height for easy viewing, and so that the customer may touch and examine the product while viewing and listening to the presentation. The apparatus for accomplishing this method meets engineering and functional requirements associated with deployment in a store where many products compete for space.Type: ApplicationFiled: November 26, 2007Publication date: July 30, 2009Inventors: David Eimerl, Jack W. Moorman

Publication number: 20050049582Abstract: A method and apparatus for providing fractional treatment of tissue (e.g., skin) using lasers is disclosed. The method involves creating one or more microscopic treatment zones of necrotic tissue and thermally-altered tissue and intentionally leaving viable tissue to surround the microscopic treatment zones. The dermatological apparatus includes one or more light sources and a delivery system to generate the microscopic treatment zones in a predetermined pattern. The microscopic treatment zones may be confined to the epidermis, dermis or span the epidermal-dermal junction, and further the stratum corneum above the microscopic treatment zones may be spared.Type: ApplicationFiled: July 9, 2004Publication date: March 3, 2005Inventors: Leonard DeBenedictis, G.

Patent number: 5264959Abstract: Temperature-insensitive, phase-matched harmomic frequency conversion of laser light at a preferred wavelength of 1.064 microns can be achieved by use of a crystal of deuterated l-arginine phosphate. The crystal is cut and oriented so that the laser light propagates inside the crystal along one of several required directions, which correspond to a temperature-insensitive, phase-matching locus. The method of measuring and calculating the temperature-insensitive, phase-matching angles can be extended to other fundamental wavelengths and other crystal compositions.Type: GrantFiled: November 25, 1992Date of Patent: November 23, 1993Assignee: The United States of America as represented by the United States Department of EnergyInventors: Charles E.

Patent number: 4510402Abstract: A pair of uniaxial birefringent crystal elements are fixed together to form a serially arranged, integral assembly which, alternatively, provides either a linearly or elliptically polarized second-harmonic output wave or a linearly polarized third-harmonic output wave. The "extraordinary" or "e" directions of the crystal elements are oriented in the integral assembly to be in quadrature (90.degree.). For a second-harmonic generation in the Type-II-Type-II angle tuned case, the input fundamental wave has equal amplitude "o" and "e" components. For a third-harmonic generation, the input fundamental wave has "o" and "e" components whose amplitudes are in a ratio of 2:1 ("o":"e" reference first crystal). In the typical case of a linearly polarized input fundamental wave this can be accomplished by simply rotating the crystal assembly about the input beam direction by 10.degree..Type: GrantFiled: June 10, 1982Date of Patent: April 9, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventors: Mark A.
