Paper Abstract

The second harmonic beam in a phase matched frequency doubler crystal travels in the direction of phase matching. If the wavelength of a focused fundamental beam is changed, the phase matching direction is changed and the harmonic beam is deflected. The deflection angle and number of pixels are derived. Experimental results ona LiI03-crystal are presented. With electro-optic wavelength tuning very fast scanners (up to 1010 pixels/sec) can be constructed. Changes of the phase matching direction can also be obtained via the electro-optic effect. This effect is investigated, and it is found that this effect is too small for the usual non-linear electro-optic crystals, but can be of practical importance for the non-linear organic crystals recently discovered.
