A Green Laser Pointer Hazard |

| Abstract: |
An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be noticed by most users of such pointers. We find that the problem derives from an unsafe design, and describe a simple method of testing for it using common household items. |
