User:Anthony Salvagno/Notebook/Research/2011/01/20/AOM Oscillation Issue
We had the laser aom and QPD in line with nothing between the components. Pranav then adjusted the AOM so that the laser would pass through the AOM crystal at different points.
Note: The square on the top is supposed to represent the AOM crystal and there is supposed to be a circle inside it indicating the position of the laser beam, but it only worked in image 5.
closest to transducer
close to transducer but near middle
middle of crystal
away from transducer but near middle
farthest from transducer slightly clipped
So it seems that the closer to the transducer the less oscillation there is and also the less drift there is.
