When using optical lasers, there is a distinction made between "direct drive" and "indirect drive" systems.

Leo aimed the optical laser carefully, and paused a moment for the anxiety rush.

Masers spread out more rapidly than optical lasers owing to their longer wavelength, and so would not have as long an effective range.

But I was speaking of optical masers-or lasers, as some people call them.

High-power optical lasers, probably a battery of them, shining back along her line of flight.

In principle, a clock tuned to the higher frequencies of optical lasers would be even more accurate.

They used a pulsed optical laser, where each pulse consisted of exactly 532,361 oscillations.

Intel researchers have made an important advance in blending silicon chip technology with optical lasers.

It is quite obvious that anybody trying to communicate in space would use optical lasers and modulate the light beam.

What you are seeing is a burst of information carried by optical laser.
