    The oscillator strengths, transition rates, and branching ratios associated with known and potential laser transitions in trivalent holmium are discussed. Recently reported laser transitions between the5F5and5I5energy manifolds are found to have an abnormally low average oscillator strength, and an alternative explanation of the laser observation is suggested.

    Pronounced absorptions in the 8-17-\mu m region are observed on surfaces of NaCl that are used as Brewster windows in chemical lasers that derive their excitation from the CS2/O2reaction. Surface reaction involves species that are formed during the chemical and photochemical processes that are active in the system. Implications regarding other reactive systems (using either chemical or electrical excitation) are also discussed. View full abstract»

    Theoretically predicted mode-dependent modulation in (Ga,Al)P waveguide modulators for which the depletion region is small compared to the guide width is demonstrated experimentally. At 10 V the measured retardations of the three lowest order modes are 0.36, 0.78, and 1.13 rad, respectively. View full abstract»

    A stable CW white laser light consisting of red (6360 Å, 6355 Å), green (5378 Å, 5338 Å), and blue (4416 Å) line spectra emitted from Cd ions has been obtained with an improved flute-type hollow-cathode He-Cd+laser tube and a broad-band optical cavity. The typical output-power level was about 10 mW, discharge conditions being 250 V and 0.6 A. View full abstract»

    Sixteen new IR laser dyes are reported. All lased successfully under excitation from a simple linear flashlamp of about 700-ns rise time. Untuned lasing wavelengths ranged from 810 to 972 nm. Laser output pulse energies from the four best of these dyes were 5-15 times greater than from diethylthiatricarbocyanine iodide (DTTC), with peak output of about 50 mJ obtained from 128-J excitation. Solvent effects with four selected laser dyes are also discussed. View full abstract»

  • Phase-matched-stimulated four-photon mixing in silica-fiber waveguides

    Stimulated four-photon mixing has been observed in silica-fiber waveguides. Phase matching is achieved by using the dispersion of the waveguide modes to compensate for bulk dispersion. The coherence lengths can be greater than 10 m and the gains more than double the usual Raman gain. View full abstract»

  • The mechanism of single-frequency operation of the hybrid-CO2laser

    The mechanism of a new method of obtaining high-power single-frequency pulses from a TEA-CO2laser is discussed. Measurements of the shape and monochromaticity of pulses from the hybrid laser which has both a TEA and a low-pressure gain section inside one resonator are presented. The mechanism of single-frequency operation of the hybrid laser is discussed with reference to numerical solutions of simplified rate equations. The low-pressure section provides gain only over a narrow range of frequencies so that a mode lying in that bandwidth builds up faster than neighboring modes to give a single-frequency pulse resembling in overall shape the normal TEA laser pulse. If the system is already lasing when the TEA discharge begins, the single-mode radiation already present rapidly grows to give a single-frequency pulse lacking a gain-switched peak.
