parametric amplifier

For example, in the early days of the communication satellite parametric amplifiers were used.

Theoretically, the efficiency of parametric amplifiers can reach over 50%.

An optical parametric amplifier is used to generate squeezing at 1064nm.

The term parametric amplifier is used because the parameters of the circuit are varied.

Why, you didn't even know about parametric amplifiers.

One such technology is the optical parametric amplifier.

Parametric amplifiers also operate by changing a parameter of the amplifier.

A parametric amplifier needs a fifth port to input the signal being amplified.

A parametric amplifier is implemented as a mixer.

They are commonly used in voltage-controlled oscillators, parametric amplifiers, and frequency multipliers.

A general nonlinear theory is formulated for the calculation of the squeezing spectrum of a parametric amplifier.

Ambient noise may be severely reduced - but never to zero - by using cryogenically cooled parametric amplifiers.

This is because in the parametric amplifier a reactance is varied instead of a (noise-producing) resistance.

These parametric amplifiers transfer effectively energy directly from the pumping laser beam to the beam being amplified.

The squeezing spectrum of a parametric amplifier, with a quantized pump field, is calculated using the Feynman-diagram technique.

Research Fellow at the University of Southampton, continuing work on optical parametric amplifiers and oscillators.

Parametric amplifiers can amplify light by hundreds of millions of times on an optical path of a few centimeters only.

Drummond, Comment on `Langevin equations for the squeezing of light by means of a parametric amplifier'.

Varactor parametric amplifiers have been developed as low-noise amplifiers in the radio and microwave frequency range.

Certain ferroelectric materials also have intriguing possibilities as optical devices, such as frequency doublers and parametric amplifiers.

Parametric amplifiers use parametric amplification.

For this reason we are proposing the establishment of a parametric amplifier laboratory as part of the Centre for Quantum Technology.

One of the long-term objectives of the research on parametric amplifiers is to generate laser pulses with power of 200 TW and higher.
