Conjugation fidelity and bistability in a high-efficiency mutually pumped phase conjugator with ring channels
Abstract:
We describe a high-efficiency mutually pumped phase conjugator with ring channels in a bird-wing incident geometry in copper-doped potassium sodium strontium barium niobate. A transmissivity as great as 35% is measured. Optical switching is obtained. The dependence of phase-conjugation fidelity on the geometric parameters and the input-beam ratio is discussed. Some suggestions are proposed to improve the fidelity further. The response times as a function of the input-beam ratio with the input beam kept constant are measured, and the least-squares minimum is used to simulate the fitting curve equations and to explain the formation of optical switching and the reduction or improvement of image fidelity.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
