    Single longitudinal mode selection of high power actively Q-switched lasers (1972)
    Springer
    Optical and quantum electronics 4 (1972), S. 249-256

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract A Pockels cell Q-switch has been operated in a manner analogous to a saturable absorber by initially keeping the cell partly open for the first 1000 or so double passes and then opening it completely at a pre-set resonator power. This then allows simple and reliable selection of a single longitudinal mode. A detailed discussion is given of the design considerations which lead to the correct choice of mode-selecting device. With three different devices, a TEM00 mode Nd:CaWO4 laser has produced 400 kW pulses in a single longitudinal mode with a shot-to-shot frequency stability of ∼ 0.01 cm−1.

    A two-step Q-switching technique for producing high power in a single longitudinal mode (1971)
    Springer
    Optical and quantum electronics 3 (1971), S. 163-169

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract An electro-optic Q-switch has been opened in two steps to allow slow pulse build-up giving, in conjunction with a resonant reflector, a high degree of mode selection in a way analogous to the use of saturable absorbers. Using this technique, a flash pumped Nd∶CaWO4 laser has produced reliable operation in a single longitudinal and transverse mode with an output power of 250 kW.

    Telescopic resonators for large-volume TEM00-mode operation (1981)
    Springer
    Optical and quantum electronics 13 (1981), S. 493-507 
    Details
    ISSN: 1572-817X

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract A stable resonator incorporating a suitably adjusted telescope gives reliable operation of an Nd:YAG laser with a large-volume TEM00 mode. The telescope adjustment is chosen to minimize the effect of focal length variations in the laser rod and at the same time ensures the optimum mode-selection properties of a confocal resonator. Simple approximations applied to the ray transfer matrices allow a detailed analysis of the resonator to be performed. This analysis yields simple design equations relating the mode spot sizes, resonator length, telescope magnification and defocusing, and diffraction losses. Experimental results show excellent agreement with the results of this analysis.

    A prism reflector of anti-resonant ring configuration (1983)

    Notes: Abstract Two identical prisms are combined to form an anti-resonant ring reflector, giving total reflection without the use of coatings or roof edges. When used as the total reflector in a Q-switched NdYAG laser this device has shown a damage threshold twice that of a multilayer reflector.
