Abstract
Microprocessor control of an iodine-stabilised ion laser is described. This control is achieved using an STD-bus based Z-80 processor and standard STD input/output cards to interface with the various laser transducers and detectors. Automatic control functions include laser wavelength selection and optimisation, laser current and intensity control, and high resolution frequency scanning with recognition of, and stabilisation to, selected saturated iodine features. Automatic switching between iodine-stabilised Kr+ ion laser wavelengths at 568 nm and 531 nm is specifically described.
