Phase-conjugating mirror with continuous-wave gain
A continuous-wave phase-conjugating mirror with gain up to 100 has been demonstrated. The mirror employs degenerate four-wave mixing of milliwatt beams mediated by the photorefractive effect in a single crystal of barium titanate of 2.2 x 2.8 x 4.2 mm dimensions at room temperature. The mirror has b...

| Zusammenfassung: | A continuous-wave phase-conjugating mirror with gain up to 100 has been demonstrated. The mirror employs degenerate four-wave mixing of milliwatt beams mediated by the photorefractive effect in a single crystal of barium titanate of 2.2 x 2.8 x 4.2 mm dimensions at room temperature. The mirror has been used to construct an image amplifier and an oscillating optical resonator which, in conjunction with a spatial filter, corrects phase aberrations inside the resonator cavity and emits a TEM(00) Gaussian mode. |
