Abstract

Traditionally, methods used for inputting gasses to Class I Laser Enclosures or exhausting gases from Class I Laser Enclosures presented problems for designers to ensure fail-safe interlock character- istics. Switches can fail and hoses can be replaced on input/output ports with the interlock feature defeated. This presents an opportunity for acciden- tal exposure to laser radiation hazards. The laser emission baffle provides a non-defeatable solution to this problem. The baffle is designed to be left in place even during maintenance or repair procedures. The baffle, detailed in the attached drawings Figures 1 and 2, allows gases to enter or exit from the enclosure without removal. If an input/output hose was not attached to the port, this device prevents any Laser energy from escaping and causing a hazard.

LASER EMISSION BAFFLE

by Don Gebbia, Frank Lotz and Robert W. Wandelt

  Traditionally, methods used for inputting gasses to Class I Laser Enclosures or exhausting gases from Class I Laser Enclosures presented problems for designers to ensure fail-safe interlock character- istics. Switches can fail and hoses can be replaced on input/output ports with the interlock feature defeated. This presents an opportunity for acciden- tal exposure to laser radiation hazards. The laser emission baffle provides a non-defeatable solution to this problem. The baffle is designed to be left in place even during maintenance or repair procedures. The baffle, detailed in the attached drawings Figures 1 and 2, allows gases to enter or exit from the enclosure without removal. If an

input/output hose was not attached to the port, this device prevents any Laser energy from escaping and causing a hazard.

  The laser emission baffle, as designed, has a series of holes drilled radially and perpendicular to the port on the circumference that allow gases to flow in or out and still maintain the light-proof integrity to classify a laser as Class I. The baffIe is a slip lit for the poft it is protecting, and is secured with set screws. As the baffle has no moving parts, it cannot fail. The baffle is an inexpensive solution that requires no support circuitry or wiring that could be the cause of failure.
