Suppression of photorefractive beam fanning using achromatic gratings
We show that achromatic grating techniques, using the 488- and 514.5-nm lines of the argon-ion laser, can suppress beam fanning while still allowing two-beam coupling to occur. The suppression is studied as a function of the ratio of the two colors used to form the achromatic grating.
