title: Faraday rotators for high power laser cavities.
abstract: The large values of Faraday rotation obtained with the use of pulsed high field magnets are shown to be applicable to the control of laser cavities. Experiments are described in which high-field magnets are operated up to 400 kOe in order to introduce large rotations in short, highly transparent optical media. With a ruby laser, interesting pulse enhancement and periodic equispaced output is observed and related to the switching rate of the field, typically 20 kOe/micro sec. Used with a cryptocyanine shutter, it is found that either a single giant pulse or a well-spaced series of pulses can be obtained. These are synchronized with respect to the varying magnetic field with fractional microsecond accuracy.
