The temporal pulse shape varies at different wavelengths, within the same wavelength, and between identical lasers. In differential absorption lidar (DIAL) measurements the variance introduced into the deduced average pathlength concentration from variation of laser pulse shape through the approximation of the normalized energy of the lidar return by sampling peak power values is small but can be significant for detecting low-level concentrations. The magnitude of this uncertainty is on the order of that caused by measurement errors on the order of a few percent.
