Abstract
A laser shield is constructed from a non-linting fabric sheet and a metal layer. The shield can be used as a laser-resistant surgical drape during laser surgery to protect the patient from aberrant laser strikes. The laser shield resists penetration by commonly-used surgical lasers, is non-reflective and flame resistant, and provides ready detection of any laser beam which strikes it.
