High power optical amplifiers are used in long distance systems.

These optical amplifiers can also be used to create Lasers.

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

He dropped near treetop level and activated the optical amplifier.

Since the late 1990s, regenerators have been largely replaced by optical amplifiers.

Over longer distances, optical amplifiers would be used to bolster the strength of the signals.

The semiconductor optical amplifier is of small size and electrically pumped.

One of the applications is for optical amplifiers.

A technological breakthrough, optical amplifiers, changed all that in the mid-1990's, about the time the Internet began making huge demands on networks.

They are also used in very high power laser systems, which use chains of optical amplifiers to produce an intense beam.

The high capacity is the result of optical amplifier technology that was developed by Bell Laboratories.

'Optical amplifiers' amplify light through the process of stimulated emission.

Optical amplifiers are important in optical communication and laser physics.

An active mirror is a thin disk-shaped double-pass optical amplifier.

By itself, this makes an optical amplifier.

Optical fibers (with special chemicals added) can be used as optical amplifiers.

"Linear optical amplifiers" using gain-clamping techniques have been developed.

"Today we have optical amplifiers and we can rapidly tune over a limited portion of the spectrum."

Optical amplifiers used newly developed lasers to excite the photons as they passed along.

By tuning an input signal to a peak of the gain spectrum, it is possible to create an optical amplifier.

There are several different physical mechanisms that can be used to amplify a light signal, which correspond to the major types of optical amplifiers.

Optical amplifiers are used to amplify an optical signal.

In contrast, an optical amplifier can amplify all of the wavelengths in a single device.

TPC-5 is an improvement over previous fiber-optic networks, however, because it incorporates optical amplifiers.

If necessary, an optical amplifier can be used to boost the downstream optical signal to cover a greater distance.
