Abstract

This paper describes a thermally compensated, servo-stabilized, single frequency argon-ion laser. Operating in a single transverse and single axial mode, the laser can supply i350 millixatts of optical power at 5145Å. or 4880Å with coherence lengths of 1000 meters. This combination of high power and high coherence makes it particularly useful for deep-field holography. Using this laser, the requirement for approximately equal path lengths for the reference beam and image beam is removed, giving the holographer a new degree of freedom.
