The new laser source generates extremely brief pulses of light.

A second interferometer uses a laser source so that the light is monochromatic.

Viewers are not always looking at the laser source.

In a disco or concert situation, the focus is not usually exclusively at the laser source.

The pupil is relatively far from the laser source.

Decades later, the advent of laser light sources answered Michelson's objections.

I went to one knee and let the mini-gun train on the laser source.

This method uses a strong laser source for optical excitation of the sample under investigation.

Spectra cannot be acquired quickly due to the monochromatic laser source which is used.

Direct mechanical displacement is measured by an external laser source and a detector.
