Talk:Acousto-optic modulator
From Wikipedia, the free encyclopedia
I changed the sin equation to bring the 2 to the top of the fraction since the distance between the high pressure regions is half the wavelength of the sound waves and m*lamda_light = s sin theta where s is the distance between the high pressure peaks
[edit] shifted frequency
A typical frequency shift varies from 27 MHz, for a less-expensive AOM, to 400 MHz, for a state-of-the-art commercial device. In some AOMs, two acoustic waves travel in opposite directions in the material, creating a standing wave. Diffraction from the standing wave does not shift the frequency of the diffracted light.
i dont get it in better devices the frequency shifting is larger? —Preceding unsigned comment added by 83.130.205.68 (talk) 11:59, 23 May 2008 (UTC)
