Phase-locking efficiency of waveguide CO2 lasers with a spatial filter
Abstract
A study was made of the efficiency of phase locking of the radiation emitted by waveguide C02 lasers with a spatial filter, considered as a function of the filter parameters and of the mismatch between the optical lengths of the individual laser cavities. Under full phase looking conditions it should be possible to reach a phase-locking efficiency in excess of 80 per cent.
