LASER SAFETY EQUIPMENT: Fiber lasers present new safety challenges

摘要

In the last few years, integration of fiber lasers into process machines has proved challenging when trying to comply with laser-safety regulatory agencies. Recent developments in active-guard technology may prove helpful. Integration of fiber lasers into material-processing systems has presented new challenges to engineers trying to comply with the requirements of the U.S. Food and Drug Administration's Center for Devices and Radiological Health (CDRH) or other international laser standards such as the International Electrotechnical Commission (IEC). Challenges include the provision for a physical beam stop or attenuator, emission indicator, and adequate protective housing. Fortunately, new developments, such as active-guard technology, or new applications of existing technology may prove helpful.
