Abstract:

Limitations of commercially available photographic materials for application in laser emission studies are described in terms of spectral response, sensitivity level, short dynamic exposure range and low tolerance to high energy densities. Commercially available XR film, which has a uniform response for visible light photography spanning nearly eight orders of magnitude, is not optimally suited for laser emission studies at 6900A nor does its high specular diffuse density allow the film to endure energies 0.1 joulesq cm. The results of studies with silver halide and photochromic emulsions and special XR film models specifically designed for use with laser emissions are summarized. The silver halide films not only have a 10 to the 9th power dynamic range of exposure, but are responsive to a broader spectral range including wavelengths in the one micron region and have exhibited toleration to energy densities of 45 joulessq cm. Further response to 10.6 micrometer was found in photochromic films.
