| 1. | Regenerative amplifiers operate by amplifying single pulses from an oscillator ( see above ).
|
| 2. | Two different designs exist for the amplifier : regenerative amplifier and multi-pass amplifier.
|
| 3. | The problem with regenerative amplifiers working at these very high gains is that they easily become unstable and start to oscillate.
|
| 4. | :: I have worked in an ultrafast laser lab, which had a pulsed laser and regenerative amplifier similar to the link provided above.
|
| 5. | 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.
