Paper Abstract

Analytical models are presented which quantitatively relate the efficiency/bandwidth per-formance of A-0 modulators to the transverse mode structure and polarization states of the incident laser beam. The cases treated include plane and elliptically polarized, He-NE (632.8 nm) and He-Cd (441.6 nm) laser radiation in either a TEM00, TEM01 or TEM10 transverse mode. For modes higher than TEM00 a significant decrease in efficiency/bandwidth occurs. The effect of power fluctuations associated with the principal polarization components of internal mirror gas laser output beams is also evaluated. Such effects present severe problems in the case of He-Ne laser beam modulation, but are less serious for He-Cd lasers. Several experimental measurements which confirm the general validity of the analyses are also described.
