Can you trigger a photogate with a green laser?

Yes. We have tested this with the Green Diffraction Laser, order code GDL-DAK, $250 and it effectively activates the photogate's photo-transistor.

A Class 2 laser is generally considered safe as the blink reflex will limit exposure to short time periods. Direct exposure (by direct or reflected light) on the eye by a beam of laser light should always be avoided with any laser, no matter how low the power.
