    The population inversion between the 3S_{2} level and the 2P_{4} level for He-Ne gaseous laser is calculated by solving rate equations in the four-level system in the steady state. Using this result, the unsaturated gain and the output power in laser oscillation as a function of discharge current are obtained for laser m... View full abstract»

  • Quantum theory of an internally phase-modulated laser - I

    A rigorous quantum-mechanical treatment of the internally phase-modulated laser is performed in terms of traveling-wave modes of the quantized electromagnetic field. A detailed treatment of the modulation process is consistent not only with the phase-locked and FM behavior of the laser, but also describes the external (to the laser cavity) frequency shifting of phase-locked light and single-freque...

  • On the optimal use of DC and RF excitation in He-Ne lasers

    Experimental results show that superposed dc excitation can improve the power output of RF excited He-Ne lasers over the total useful life of the units. The results show that the variable dc excitation results in about twenty percent increase in laser power out. View full abstract»

    An intracavity voltage-tunable laser frequency and polarization selector consisting of a birefringent electrooptic crystal and a partial polarizer is presented. The polarization eigenmodes and eigenvalues of this system have been calculated and verified by experimental results showing electronic frequency tuning of a CW Nd:YAG laser over at least 130 GHz at 1.06 micron. Electronic polarization swi... View full abstract»

  • Continuous operation of a long-lived CO2laser tube

    A sealed-off CO2laser tube was operated with continuous, almost constant, power output at 10.6 μm for more than 1000 hours. A Ni cathode that was maintained at 300°C acted as a catalyst to regenerate CO2back into the tube from the oxygen and carbon monoxide formed in the discharge. By the time 1100 hours of operation had passed, 92 percent of the original CO... View full abstract»

  • Theory of laser mode coupling produced by cavity-length modulation

    Laser mode coupling produced by oscillatory motion of a cavity mirror is analyzed by means of a quasi-normal mode expansion of the cavity field which satisfies the time-dependent boundary conditions. The quasi-normal mode-coupling equations are identical in form to the coupled-mode equations for the phase-modulated fixed length laser. View full abstract»

  • Nonlinear optics, anharmonic oscillators, and pyroelectricity

    An anharmonic vibronic oscillator model is set up and used to derive general expressions for nonlinear susceptibilities. The system is handled both classically and quantum-mechanically, and the results are shown to agree. It is shown that, when one of the interacting fields has a frequency close to that of an optical phonon, the nonlinear susceptibility is dominated by the same term in the anharmo...
