A green laser pointer hazard

  title={A green laser pointer hazard},
  author={Jemellie Galang and Allesandro Restelli and Edward W. Hagley and Charles W. Clark},
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.An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use.

Green lasers are beyond power limits mandated by safety standards

Relevant professional bodies ought to advocate more strongly for stringent testing, quality control and licensing of DPSS lasers with a view towards government intervention to banning green laser pointer use.

Progress in a Development of a Laser-Based Weed Control System

The results demonstrate the potential of CO2 laser as promising alternative for an efficient weed control and a laser triangulation system based on laser pointers is proposed as a tool for distance measurements to estimate the distance of cutting targets.

Examining the interaction of different factors on pointing precision when using handheld laser pointers

Objective Laser pointers are common teaching tools used during lessons. The pointing precision may influence the teaching effectiveness. In this study, we examined the effect of four external

Effect of Green Light from Doubled Frequency Neodymium-Doped Yttrium Aluminum Garnet (Nd:YAG) Laser in the Nanosecond Range on Rabbit’s Lens –In Vitro Study

Iradiation with frequency doubled Nd-YAG green laser seem to be cataractous if the lens is exposed to laser that is intense enough to warrant thermal protein aggregation, according to rabbits’ lenses after short and prolonged exposures.

Spectral characteristics of a microchip Nd:YVO4 laser

Frequency-doubled light at 532 nm from the microchip Nd:YVO4 lasers is a promising candidate to replace the widely used He-Ne lasers in length metrology due to their superior characteristics,

A variant of Young’s double slit experiment for educational purposes

We describe a variant of the classical Young’s double slit experiment that can be easily realized in any classroom, in order to evidence the wave nature of light. The proposed apparatus and its

Maculopathy following exposure to visible and infrared radiation from a laser pointer: a clinical case study

Loss of retinal function following laser pointer injury may not always be detectable using standard electrophysiological tests, despite severe focal damage to the central retina visible fundoscopically and with OCT.

Because the authors have no proven treatment for most injuries to the retina, it must continue to strongly emphasize the use of wavelength-specific protective goggles to try to prevent future eye injuries.
