Abstract
A laser imaging apparatus, such as a laser scanner or laser printer, includes a gas or diode laser which produces a laser beam and an optical system for directing the laser beam onto a object to be scanned or printed. The laser beam is encompassed in a sealed housing from the laser's output to a point at which the beam is no longer subjected to turbulent environment in order to eliminate laser beam pointing instabilities resulting from a turbulent environment caused by thermal sources, cooling fans, etc.
