Argon-ion, copper-vapor, and frequency-doubled neodymiun:yttrium aluminum garnet (Nd:YAG) lasers have been examined for efficiency in latent fingerprint detection. All three types of laser are found to be effective.
Abstract
Argon-ion lasers have the greatest power and range of useful wavelenths while frequency-doubled Nd:YAG lasers offer crime scene capability. On rare occasions latent prints observable under the argon-ion laser are not visually discernible under the Nd:YAG laser, but can be located with a sensitive televison camera. Once located, photography of such prints is straightforward. (Author abstract)
