    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)

    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.
