    Amplification of 10.6-μm radiation in a metallic waveguide and waveguide CO2-laser action was achieved by excitation of the CO2(0001) mode by vibrational energy transfer from metastable N\min{2}\max {\ast }(\upsilon = 1) molecules. Excitation of N2was accomplished in a separate dc discharge tube. The N... View full abstract»

    This paper describes an experimental investigation of a pulsed CS2/O2chemical CO laser initiated in a high-pressure double-discharge TEA-laser system. A distributed volumetric discharge was obtained and yielded a maximum pulse energy of 115 mJ with a chemical efficiency of 4.5 percent, an electrical efficiency of 2.5 percent, and a specific output energy of 1 J/1.

  • A canonical formulation for analyzing multielement unstable resonators

    A simple but general formulation for the unified analysis of many different varieties of unstable optical resonators is obtained by expressing the round-trip Huygens' integral for the resonator in terms of the round-trip paraxial ray matrix. Complicated multielement resonators, ring resonators, and unstable resonators with variable-reflectivity output mirrors are thereby all reduced to a single eq... View full abstract»

  • Analysis of intensity fluctuations in a junction laser with low quantum-efficiency regions

    Publication Year: 1976 , Page(s): 47 - 53
    Cited by:  Papers (1)

    Fluctuation spectra due to quantum shot noise in the output from a junction laser are calculated using rate equations for a non-uniform double-sectioned laser with a low quantum-efficiency region. The pumping-rate dependence of the fluctuation spectra for the non-uniform model is found to be roughly the same as that for the ordinary uniform model. The degradation process is then simulated using th... View full abstract»

    We have generated 1202.8-Å radiation, one-half the frequency of the 1s^{1} S_{o}-2s^{1}S_{o} forbidden transition in He, using resonantly enhanced four-wave optical mixing in Hg vapor. Peak powers of 300 W in a ∼ 15-ps pulse have been achieved using a tunable narrow-band source consisting of a parametrically amplified commercial dye laser. The depe... View full abstract»

    The ion spectra of He-CO-laser discharges with and without small addition of O2is presented. It is shown that upon addition of oxygen the dominant positive charge carriers in the discharge are O2+ions. It is argued that the oxygen ion O2+is populated in stage processes: the ...

    Optical pumping of Nd:YAG by electrodeless are lamps is described. The lamps are annular, filled with 1-5-atm pressure of krypton and excited with 27-MHz electrical energy which is coupled to the lamp with approximately 80-percent efficiency. Optical energy is coupled from the lamp to the rod by a diffuse reflecting scheme. Overall efficiency and power output of the device are comparable to the dc... View full abstract»

    Ninety-nine new far infrared (FIR) laser lines from 227 μm to 1.965 mm have been observed in CH3CN, CH3CCH, CH3Cl, CH3Br,and CH3I by optically pumping these gases with CO2-laser pulses of 150-μs duration. View full abstract»

  • Continuous-wave CH3F waveguide laser at 496 µm: Theory and experiment

    The kinetic processes controlling the conversion of CO2pump radiation into far-infrared (FIR) radiation in optically pumped waveguide lasers are discussed. It is found that pump saturation and excited-state FIR absorption play major roles in limiting the conversion. Good agreement between theory and experiment was obtained over a wide range of pump powers, gas pressures, and mirror refl... View full abstract»

    Output power versus current characteristics of a multiple-anode hollow-cathode He-I2laser have been studied using quasi-continuous excitation. Oscillation has been obtained on a total of 25 transitions of I+ranging in wavelength from the blue to near infrared and including 9 new CW transitions. For all transitions, upper level excitation is attributed to thermal-energy charge... View full abstract»

    Volumetric photoionization in CO2-laser gas mixtures by UV emission from bare sparks was studied in two ways: by spectroscopic emission and absorption measurements, and by direct collection of photoionized electrons. The physical processes were understood sufficiently to permit prediction of initial electron distributions in arbitrary geometries of CO2, N2, He gas ... View full abstract»

    A modified distributed-feedback (DFB) laser, termed the multiply resonant distributed-feedback (MRDFB) laser, is described and demonstrated. The MRDFB-laser cavity incorporates a doubly periodic index-of-refraction variation which leads to the colinear generation of several preselected laser wavelengths simultaneously. A theoretical analysis of the MRDFB laser is given using the coupled-mode forma... View full abstract»
