Abstract
The invention relates to an arrangement for and a method of doubling the frequency of a light wave, for example to convert infrared light originating from a laser into green light. To that end a fundamental light wave is circularly polarized and passed through a non-linear optical medium, a second harmonic wave then being formed. The non-linear optical medium is formed from a centrosymmetrical material, whose molecules or molecular groups evidence chirality.
