regenerative amplifier वाक्य

Regenerative amplifiers operate by amplifying single pulses from an oscillator ( see above ).
Two different designs exist for the amplifier : regenerative amplifier and multi-pass amplifier.
The problem with regenerative amplifiers working at these very high gains is that they easily become unstable and start to oscillate.
:: I have worked in an ultrafast laser lab, which had a pulsed laser and regenerative amplifier similar to the link provided above.
The first stage is a regenerative amplifier in which the pulse circulates 30 to 60 times, increasing in energy from nanojoules to tens of millijoules.
