They switched to using an infrared laser for the 2009 competition and will continue to do so in 2010.

A second, more efficient and correct method is to use an infrared laser placed at ground level.

These are usually two near infrared lasers and maybe an optical amplifier.

Although not as common, infrared lasers are used due to their softer mode of ionization.

Visible and infrared lasers are at the core of information technology.

They then visited the only other building, where the more powerful infrared laser is housed.

They used another infrared laser to create an optical trap for the bead.

Other types of spot sensors, like infrared lasers and detectors that sense vehicles by their effect on a magnetic field, are also in use.

The most common method is to use some form of radiation, such as infrared, lasers or radio waves, to guide the missile onto its target.

An infrared laser is traced along the seam, causing the two sides to weld together.
