    A theoretical model that accounts for the experimentally observed features of the 5106-Å pulsed copper vapor laser has been devised. The electron excitation and ionization cross sections used in the theory were calculated by the use of the classical Gryzinski-type methods. View full abstract»

    Experiments and approximate analysis are given for spherical aberration interference rings and for convection distortion arising in the thermal self-defocusing effects produced by laser beams passing through materials of finite loss. The importance of these thermal effects for moderate-power beams in materials of relatively low loss is stressed. View full abstract»

    The life expectancy of a sealed CO2laser tube depends, to a great extent, on the interaction of the molecules existing in the discharge at the cathode. The data reported here indicates that after operation of a sealed laser, only CO and O2are formed in concentrations comparable to the initial fill gases of CO2, N2, and He. The CO, CO2, and O2, in particular, were found to be completely adsorbed at the Ni cathode within several hundred hours of tube operation. A loss of 10.6 μm power output accompanied this adsorption. As expected, the process was reversible to a degree since the laser resumed operation at the initial power level after the cathode region had been heated to 300°C. This process of adsorption-desorption was repeated several times up to an accumulated operating time of 705 hours. During this time, the power output remained at a substantially constant value. However, the loss of CO2by carbon deposits ultimately means an end to tube life. View full abstract»

    Fluorescence from CO2molecules excited by transfer from heated nitrogen has been observed. Insofar as thermal excitation of nitrogen can be accomplished by chemical means, this process may be utilized to implement a chemically excited laser. View full abstract»

  • Proposal for generation of intensive single-frequency beam by second harmonic generation of an FM laser beam

    An arrangement that allows the generation of a single-frequency beam at the second harmonic is proposed. Essentially, frequency addition is performed of two signals that are frequency modulated with equal and opposite frequency excursion. For maximum efficiency, the modulator and the nonlinear crystal are arranged inside optical resonators for fundamental and harmonic frequencies. View full abstract»
