DBM1172-G41-9
Dual Beam IR Acousto-Optic Modulator
The Dual Beam Modulator incorporates a novel acoustic beam steering technique to allow the user to switch between the +1 and -1 Bragg orientations. Under electronic control, the user can generate two sequential output beams from a single laser input. Independent modulation levels can be applied to the A and B first order outputs.
