    A mechanism of laser triggering of spark gaps in which laser-produced ions play the dominant role is investigated for several electrode materials. Spark channels due mainly to laser-produced electrons and channels due mainly to laser-produced ions are clearly distinguished by high-speed shadowgraph techniques. View full abstract»

    The saturated gain constant of the carbon dioxide laser is calculated using a thermodynamic approach. At low electron densities the gain constant is found to saturate according to a well-known and simple function. At higher electron densities, however, a more complicated form is assumed. The calculations are found to agree well with measured saturated gain. View full abstract»

    An analysis of optical second-harmonic generation internal to the laser cavity is presented. It is shown that the maximum second-harmonic power generated in this way is equal to the maximum fundamental power available from the laser. Further, it is found that there exists a value of nonlinearity that optimally couples the harmonic out for all power levels of the laser. The magnitude of the nonline... View full abstract»

    The effect of inserting an element exhibiting induced absorption into a Q -switched laser cavity is investigated theoretically and experimentally. The rate equations are solved assuming two types of nonlinear loss, one being proportional to the square of the laser intensity and the other being proportional to the product of laser intensity and density of excited...

    An experimental study of noncritically phase-matched ( \theta_{m} = 90\deg ) second-harmonic generation is described, in which the theoretical predictions of Boyd and Kleinman with regard to strength of focusing and effect of mismatch are closely verified. Radiation at 1.084 μ from a He-Ne laser was employed to generate light at 542 nm in LiNbO... View full abstract»

    Two methods of information storage in a holographic memory device are discussed: consecutive storage of individual binary numbers on the same hologram, and parallel storage of masses of binary numbers on individual holograms. Optical setups of respective memory devices are described. Experimental results of the investigation of these setups are presented. View full abstract»

  • Guide lines for the selection of acoustooptic materials

    Guide lines are presented for the selection of promising new acoustooptic materials for device applications. Previously, the selection of materials was based primarily on availability and intuition. Now it is possible to estimate an approximate acousto-optic figure of merit for a material knowing only its chemical composition and density. One of the first applications of these guide lines led to a... View full abstract»

  • Proposed method for measuring picosecond pulsewidths and pulse shapes in CW mode-locked lasers

    A new method is proposed for measuring the widths, and possibly even the detailed shapes, of picosecond pulses in CW mode-locked lasers. The pulses are passed through an electro-optic modulator, which is biased for zero transmission with zero applied voltage, and which is driven at a harmonic of the pulse-repetition frequency. The variation in average light transmission through the modulator is mo... View full abstract»

  • Line narrowing in a phase-locked laser

    The 890-GHz line of a HCN laser has been phase locked to a multiplied standard frequency with a wide bandwidth phase-lock loop. Due to the wide bandwidth loop, linewidths of the beat between the laser and the multiplied frequency standard have been narrowed to less than 50 Hz. View full abstract»
