First, two AAA batteries fuel a diode laser -- similar to a standard red laser pointer -- which emits infrared light at a wavelength of 808 nanometers. That light gets funneled into a crystal of a ...

Twenty years ago, a green laser would set you back $100,000 and occupy a good-sized dining room table. Today, you can buy a green laser pointer the size of a ball point pen for $15. These devices ...

Researchers at the National Taipei University of Technology in Taiwan have transmitted data using lasers -- not high-powered, laboratory-dwelling lasers; handheld, AAA-battery laser pointers.

The lasers are powered by three AA batteries, ... Near infrared Light causes nitric oxide to form in the blood vessels, which is interpreted by the body as a regeneration signal.

The new MambaTM IR from Coherent is a 525 Watt (at 1064 nm), diode-pumped, solid-state laser that delivers an unmatched combination of high reliability, long lifetime and minimal maintenance downtime.
