Abstract
A thermal printer is disclosed which is particularly suitable for making slide transparencies. The printer includes a laser which provides the necessary thermal energy to effect a transfer of dye from a donor element to a receiver element. A beam from the laser passes through suitable optics and is scanned onto the receiver element by a galvonometer. In order to insure the transfer of dye from the donor at a suitable resolution and with sufficient speed, a relatively high-powered single transverse mode coherent laser is used.
