    Previous analyses of the large signal operation of optical parametric oscillators have considered uniform plane-wave pump beams. These analyses are not adequate to describe the behavior of efficient pulsed oscillators pumped by beams having nonuniform intensity profiles and pulse durations that are short enough that the steady-state transverse modes of the oscillator cavity do not become establish...

    A novel description, based on the Doppler effect, is given for laserQswitching by a rotating mirror. Fourier analysis yields a relation between the width of the pulseDeltat_{1/2}and the angular velocity of the mirrordot{theta}. It is shown that for laser emission having a Gaussian spatial amplitude profile the temporal shape of aQ-switched pulse is also ... View full abstract»

    A study of the nonlinear properties of cuprous halides in the near infrared (YAG Nd3+laser) and in the medium infrared (CO2laser) is presented. The second-order susceptibilities have been compared to those of quartz and GaAs. Coherence lengths were measured at 1.06 μ and for the four principal transition lines of CO2laser. In addition some linear parameters su... View full abstract»

    A Ge acoustooptic pulse modulator has been constructed and tested at 3.39 and 10.6 μm. A pulse rise time of 20 ns and deflection efficiency of 11 percent per watt of RF drive power when operating at 10.6 μm were realized. View full abstract»

  • Time duration of output pulse in electron-beam-pumped CdS laser

    Publication Year: 1971, Page(s):118 - 122

    Time duration of the output pulse of electron-beam-pumped CdS laser was investigated. It increased with increase of the excitation current density and was of the order of 100 ns at the beam voltage of 25 kV. It was shown experimentally that the quenching of the laser oscillation is due to the rise of the threshold current density as the result of the temperature rise in the active region of the cr...

  • On the possibility of phase-matched infrared mixing using induced birefringence

    The possibility of inducing sufficient birefringence in acentric cubic crystals to permit the phase matching of nonlinear infrared mixing is examined. It is shown that the electrooptic effect is inadequate for this, while phase matching by uniaxial stress is unlikely but cannot be ruled out. View full abstract»

    Vibrationally excited Cl2was found to strongly decrease the gain in the CO2laser amplifier whereas an increase in gain was produced by vibrationally unexcited Cl2. The results are interpreted in terms of the near resonant V-V energy transfer between Cl2and the ν2mode of CO2. View full abstract»
