The beam passes through the modulator followed by a polarizer. A Model 3211 broadbandmodulator driver is used to drive the modulator. M O D U L A T O R S New Focus™ amplitude modulators are specifically designed for high performance at modulation frequencies of up to 200 MHz. The Model 4102/4 broadband amplitude modulator can be operated from DC to 200 MHz. The Model 4101/3 is a resonant device that can be built to operate at any frequency from 0.01 to 200 MHz. The crystals in these modulators are mounted at 45° so that your input polarization can be either vertical or horizontal. To minimize thermal birefringence, we use two matched crystals arranged in series. This results in amplitude modulators that exhibit less than 1 mrad/°C of temperature-dependent polarization rotation.
