Alignment requirements for mode matching in a confocal fabry-perot interferometer.
By careful consideration of the precision of available alignment apparatus, mode matching can be accomplished most easily. A function representing the degree of mode matching in a confocal Fabry-Perot interferometer is defined and then evaluated as a function of the angular and translational alignment errors. A method is given for optimizing the beam diameter to take advantage of the available precision of specific instruments. Experimental verification is given for a specific case.
