| Term (EN) | gaussian beam |
|---|
| Definition (EN) | A beam of optical radiation whose electric field amplitude distribution is Gaussian when measured across a cross section.
Note. — When such a beam is circular in cross section, the amplitude is :
Е(r) = Е(0) ехр [— (r/w)2]
where r is the distance from beam centre and w is the radius at which the amplitude is 1/e of its value on the axis. |

| Term (SR) | Gausov snop |

| Definition (SR) | Snop optičkog zračenja koji ima Gausovu raspodjelu amplitude električnog polja kada se mjeri preko poprečnog presjeka. Napomena — Kada je takav snop kružnog poprečnog presjeka, amplituda je:
Е(r) = Е(0) ехр [— (r/w)2]
Gdje je r udaljenost od centra snopa, w je radijus pri kom je vrijednost amplitude 1/e od njene vrijednosti na osi. |
