Gaussian beam diffraction length

The output beam of a laser oscillating in the fundamental TEMgQ-mode shows a Gaussian intensity profile (see Sect.5.11). If the Gaussian beam is properly matched to a focusing system with aperture d and focal length f, a diffraction-limited focal spot of diameter dQ 2(f/d)x can be reached. With a microscope objective for example, with f/d = 1, focal spot sizes of Wq = dQ/2 =... [Pg.649]

A beam of a TEMqo laser (Vol. 1, Sect. 5.3) with a Gaussian intensity profile is focused to a diffraction-limited spot with the diameter d 2Xf D by an adapted lens system with the focal length / and the limiting aperture D. For example, with... [Pg.630]
