Abstract

A light beam and its second harmonic can create a semipermanent dc electric field inside glass. This dc electric field is responsible for the unexpected production of second-harmonic light in the glass. We determine the transverse spatial shape of this photoinduced dc field inside a bulk sample of germanium-doped fused-silica glass.

Figures (5)

Fig. 1
Fig. 1

The dc electric field produced from the charge distribution given by Eq. (2) below. With this dc field shape we successfully predicted the results of six experiments.

Fig. 2
Fig. 2

Comparison of the predicted and observed second-harmonic signals for the case of a vertically oriented reading beam probing different regions of the photoinduced dc field and viewing through a vertically oriented polarizer.

Fig. 3
Fig. 3

Same as Fig. 2, except here we flipped both the reading-beam polarization and the analyzing polarizer to horizontal. The contour plots show a four-peaked distribution. The peaks are imperfectly resolved because of the finite size of the probing beam.

Fig. 4
Fig. 4

Photographs of the observed and predicted far-field mode patterns. We oriented the analyzing polarizer horizontally and photographed the far-field pattern of generated green light. The arrow indicates the reading beam’s polarization.

Fig. 5
Fig. 5

Comparison of the observed (circles) and predicted (curves) second-harmonic signals versus the reading beam’s polarization using either (a) a vertical analyzer or (b) a horizontal analyzer.
