Quantitative Evaluation of a Time-Dependent Eye Hazard Posed by Laser Pointers.

A novel test methodology was developed for quantitative evaluation of critical radiant power characteristics as a function of time for diode pumped solid state (DPSS) laser pointers. It is based on a simultaneous measurement of time-dependent radiant power characteristics of multi-wavelength spectral components emitted by DPSS laser pointers. The authors tested green DPSS laser pointers, which emit three spectral components at the fundamental near-infrared (1064-nm), pumping near-infrared (808-nm), and second-harmonic green (532-nm) wavelengths.
