ABSTRACT:
In a device for doubling the frequency of a light wave, a fundamental light wave 2 originating from a laser light source 1 is guided through a nonlinear optical medium 5 while forming a second harmonic wave 6. The nonlinear optical medium is formed from a polymer network and elements having a great hyperpolarizability. In the device, phase matching is realised by the application of a polymer network having a helical structure. The pitch of the helical structure is adapted to the phase-matching conditions by the selection of the polymerization conditions during the formation of the network.
