Laser pointer maculopathy - on the rise?

Pediatric Bilateral Blue Laser Pointer-Induced Maculopathy

BACKGROUND We report the first case of pediatric bilateral blue laser pointer maculopathy with complete resolution of visual symptoms. CASE A 12-year-old boy presented with bilateral decreased visual acuity and central scotomata after blue laser pointer exposure. He was treated with a Medrol Dosepak and topical nonsteroidal anti-inflammatory drug (NSAID), with gradual visual acuity improved f...

A quantum laser pointer.

The measurement sensitivity of the pointing direction of a laser beam is ultimately limited by the quantum nature of light. To reduce this limit, we have experimentally produced a quantum laser pointer, a beam of light whose direction is measured with a precision greater than that possible for a usual laser beam. The laser pointer is generated by combining three different beams in three orthogo...

A Green Laser Pointer Hazard

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 this infrared emission derives from the design of the pointer, and describe a simple method of testing for infrared emissions using common household items.
