| 1. | This larger signal is often exploited to produce a stronger second harmonic signal.
|
| 2. | The second harmonic not only has twice the frequency but also twice the phase.
|
| 3. | Second harmonic generation leads to doubling of the frequency of infrared carbon dioxide lasers.
|
| 4. | In addition there is a control to vary the amount of second harmonic distortion.
|
| 5. | Optical rectification also occurs on metal surfaces by similar effect as surface second harmonic generation.
|
| 6. | In 1993, Lewis examined the second harmonic response of delicious styryl dyes in electric fields.
|
| 7. | The second harmonic can be used to reduce the overlap with edges with finite sharpness.
|
| 8. | In a push pull amplifier this second harmonic distortion is cancelled in the output transformer.
|
| 9. | The 8 bar subject starts in minims with a second harmonic half in slow quavers.
|
| 10. | The resulting measured second harmonic signal contains the second harmonic component from the buried interface alone.
