AO MODULATORS

When aligned at the Bragg angle that correctly corresponds to the laser wavelength and RF frequency being applied, the AO modulator diffracts a portion of the beam passing through it (zeroth order) into an adjacent location (first order). The first order beam is normally used for most applications. The intensity of the first order light is controlled by the amplitude of the RF signal. Either digital (on-off) or analog (video) AO modulation of the first order spot can be produced, depending on the type of driver selected.
