Characterizing Lasers that Emit Widely Diverging Radiation
Abstract
It is often difficult to accurately measure the power emitted from mid- and long-wave IR lasers because their inherently large radiation divergence. This is simply due to the fact that experimental geometry limits the solid angle of the emitted radiation that the sensitive area of a power meter can capture. However, one can confidently estimate the total power emerging from a widely diverging laser by integrating the power of an elliptically symmetric Gaussian beam that is incident on the meter's sensitive surface.
