Laser surgery is not an option since lasers emit ultraviolet rays.

Class I - These lasers cannot emit laser radiation at known hazard levels.

A laser emits light, which consists of an oscillating electric field.

I would say no since the laser is emitting light in the form of photons which have no mass.

A laser emits a laser beam into the air.

This "switch" is necessary since each laser of the array emits at a different output aperture.

However, things are far from perfect, as these particular lasers emit colors which just so happen to be ignored by most molecules.

This laser usually emits infrared waves at a wavelength of about 1064 nanometers.

In contrast, lasers can emit beams with divergences of 0.2 degrees or less.

To read, the laser is operated at a lower intensity, and emits polarized light.
