Paper Abstract

Copper vapor lasers are being used in forensic applications at more than thirty regional, state and national level forensic science laboratories (crime labs) in the United States, Israel and Japan. These high gain lasing medium systems provide desirable operational and maintenance features. The green line produced by copper vapor lasers allows use of latent fingerprint inherent and chemically induced luminescence techniques developed for argon ion lasers. The yellow line has developed latent fingerprints which would not luminesce at blue-green wavelengths, and is better suited for some forensic examinations such as ink differentiation involving forgeries and document alterations.
