    Abstract: An optical transmitter is disclosed including a widely tunable laser coupled to a periodic optical spectrum reshaper (OSR) to convert frequency modulated pulses from the laser into amplitude modulated pulses. The laser is tuned to generate pulses corresponding to passbands of the OSR spanning a wide range of frequencies. The laser includes a gain section having an optical path length substantially shorter than the total optical path length of the laser. The laser may be a Y-branch laser having reverse-biased sampled gratings or ring resonator filters tuned by stripe heaters. The laser may also include a reflective external cavity section tunable by modulating the temperature of ring resonators or etalons. The OSR may be integrally formed with the external cavity of the ECL laser.

    Abstract: A third harmonic ultraviolet laser of semiconductor double end face pumping comprises a semiconductor pumping module (1), an optical coupling system (3), fundamental gain-medium crystals (5,6), a second harmonic nonlinear crystal (10), a third harmonic nonlinear crystal (13), a wave plate (11), a modulation device (7), laser resonant cavity mirrors (4,9,14), and an ultraviolet laser reflecting mirror (12). The pump-light emitted by the semiconductor pumping module is transmitted into the optical coupling system, then collimated and focused by the optical coupling system, and incidents directly on the end faces of the fundamental gain-medium crystals. The light emitted by the excited fundamental gain-medium crystals forms fundamental frequency light beam via mode selection of the laser resonant cavity mirrors, and the modulated laser beam is obtained by the modulation function of the modulation device. The modulated fundamental frequency laser beam is converted to green laser beam via the second harmonic nonlinear crystal and is polarized by the wave plate. The fundamental frequency laser beam and green laser beam which are the same polarization are incident into the third harmonic nonlinear crystal, thereby performing sum-frequency and generating third harmonic ultraviolet laserbeam.

    Abstract: A method of fabricating micro-plasma discharge devices (90) and arrays. The method employs techniques drawn from semiconductor device fabrication, such as chemical processing and photolithography, to produce arrays of devices inexpensively. An interdigitated electrode array (16, 18) is deposited on a first substrate (14). Cavities are formed in a second substrate (34) by laser micromachining, etching or by chemical (wet or dry) etching and the second substrate (34) is overlaid on the electrode array. The inter-electrode spacing and electrode width are set so that each cavity has at least one pair of electrodes underneath it to excite a micro-plasma discharge in the cavity. The need to precisely register the two substrates are thus avoided.

    Abstract: An optical parametric oscillator (14) includes a source (10) of coherent energetic pump optical signals and an optical resonator cavity which includes a set of optical parametric amplifying (OPA) crystals (20a, 20b) and a set of optical elements (22, 24, 26) such as mirrors disposed along an optical path. The optical elements are configured (1) to direct an oscillation optical signal (28) generated by the OPA crystals along the optical path, (2) to provide input coupling of the energetic pump optical signals (12a, 12b) such that each energetic pump optical signal travels through only one of the OPA crystals to result in a corresponding depleted pump optical signal, and (3) to provide output coupling of the depleted pump optical signals (18a, 18b) to prevent each depleted pump optical signal from traveling through more than one of the OPA crystals. Resonator cavities have multiple-leg configurations, including "L" and "U" shapes, and either linear (or standing-wave) or ring architectures. The pump source may employ wavefront division or alternatively amplitude division of a single relatively high-power optical pump beam.

    Abstract: A compact mid-IR laser device utilizes a quantum cascade laser to provide mid-IR frequencies suitable for use in molecular detection by signature absorption spectra. The compact nature of the device is obtained owing to an efficient heat transfer structure, the use of a small diameter aspheric lens and a monolithic assembly structure to hold the optical elements in a fixed position relative to one another. The compact housing size may be approximately 20 cm x 20 cm x 20 cm or less. Efficient heat transfer is achieved using a thermo-electric cooler TEC combined with a high thermal conductivity heat spreader onto which the quantum cascade laser is thermally coupled. The heat spreader not only serves to dissipate heat and conduct same to the TEC, but also serves as an optical platform to secure the optical elements within the housing in a fixed relationship relative on one another. A small diameter aspheric lens may have a diameter of 10 mm or less and is positioned to provided a collimated beam output from the quantum cascade laser. The housing is hermetically sealed to provide a rugged, light weight portable MIR laser source.
