NIST Researchers Measure High Infrared Power Levels from Some Green Lasers

Caption

IR leakage: (Top) Photo from an ordinary camera shows light from a green laser diffracted into several spots. The green laser pointer is visible in the foreground. (Bottom) The same vignette photographed by a webcam with no infrared-blocking filter reveals intense diffraction spots from 808nm infrared light, invisible to the eye.
