Abstract

Nondegenerate four-wave mixing in fluorescein-doped glass was used to demonstrate frequency- dependent beam steering and tilt/focus phase control. An argon-ion laser at 457.9 nm provided the probe beam and one of the pump beams. An argon-pumped dye laser, tunable from 560 to 615 nm, provided the second pump beam. The conjugate emerged at the same wavelength as the dye laser and at a frequency tunable, phase matching steering angle. It was shown conclusively that this beam was due to four-wave mixing.
