Paper Abstract

The development of the field of holography has depended on the coherence of laser light. The most meaningful attribute of coherence for holographers is the coherence length. Commonly, coherence length is regarded as the maximum optical path difference between two beams, such as those in a Michelson interferometer, that results in a discernable interference pattern. Herein we discuss two direct holographic methods of measuring coherence length, each yielding visually observable results. We begin by examining several theoretical models for laser spectral line-widths and the corresponding derivation of coherence lengths.
