AN ESTIMATE OF THE ATMOSPHERIC PROPAGATION CHARACTERISTICS OF 1.54 MICRON LASER ENERGY
ARMY ELECTRONICS COMMAND WHITE SANDS MISSILE RANGE NM ATMOSPHERIC SCIENCES LAB
Pagination or Media Count:
Potential atmospheric effects on the propagation of electromagnetic radiation at 1.54 micron wavelength are examined. The results of transmission measurements by various investigators, as reported in the literature, coupled with theoretical calculations are applied to estimate the transmission characteristics for erbium ion Er laser radiation in this region. The output of the Er laser at 1.54 microns is discussed in some detail. Predominant attenuation mechanisms are found to be aerosol absorption and aerosol scattering. Contributions from five investigations of atmospheric transmission in this region are summarized. Nonlinear effects are not considered.
