    A CW transverse-flow chemical CO laser based on the CS+O→CO+S(+75-kcal/mole) reaction has been studied. Power output is 4.5 W with a gas flow of 70 l/min at 5.4 torr. The output occurs in the 3-2 to 14-13 vibrational transitions. Gain measurements have been made for a number of lines. The maximum observed gain coefficient is 0.006 cm-1. The variation of the laser output with a nu... View full abstract»

    An original frequency-mixing technique is described which conveniently measures the third-order optical susceptibility of any transparent material. Results are presented for χ1111(3)(-ω3, ω1, ω1, -ω2) in a number of materials. These measurements permit estimates of the nonline... View full abstract»

    Various models of a passively mode-locked quasi-continuous laser are discussed and the evolution of pulses in various cavity configurations is traced. In certain circumstances, the combined action of amplifier and absorber saturation is shown to lead to rapid pulse compression even when the pulse duration is far shorter than the relaxation time of either nonlinear component. The results are in goo... View full abstract»

    A nitrogen-laser-pumped dye laser has been made to operate in the rotationally symmetric TE01 or TM01 modes. The modes are preserved as the laser wavelength is varied. The mode selector allows convenient switching from one mode to the other. The theory of the operation of the mode selector is described. View full abstract»

  • Proposed CO2-laser standing-wave intracavity coupling modulator for a 53-GHz CW signal

    Tunable IR signals can be generated by the proposed arrangement comprising a CO2 laser and a tunable millimeter-wave cavity coupling modulator. The position of the modulator within the laser cavity was found to be critical but can be optimized. Under optimum conditions, 2.5 mW (8.0 mW) can be expected in each sideband with 1-W drive power for GaAs (CdTe) crystals at bandwidths of 21 GHz... View full abstract»

  • Heterodyne detection experiments at 118.6 um in Ge:Ga

    The observation and quantitative measurement of optical heterodyne detection in the far infrared (IR) (λ=118.6 μm) using a Ge:Ga detector are reported. The experimental results fall below theoretical predictions; the discrepancy is explained in terms of the NEP of the detector used and the low value of local oscillator power available in the experiments.

    CW laser action is reported for N,N'-di-β-phenylethylrhodamine in an ethanol-water binary solution. Performance appears to be competitive with Rhodamine 6G, with an output wavelength and tuning curve slightly to the blue relative to Rhodamine 6G. View full abstract»
