<p>As shown in the figure, a laser imageable tuned optical cavity thin film (11) for use for a laser producing laser radiation at a laser wavelength comprises a flexible sheet of plastic (12) having first and second surfaces (13 and 14) serving as a film substrate. A thin film stack (16) is disposed on the first surface of the film substrate and comprises a first vacuum-deposited metal layer (17) carried by the first surface. It is also comprised of a dielectric layer (18) deposited on the first metal layer. A second semi-opaque metal layer is vacuum-deposited onto the dielectric layer. The thin film stack is tuned to provide maximum absorption at the laser wavelength.</p> |
