The rise time of the modulator is simply deduced
by the necessary time for the acoustic wave to
travel through the laser beam. For highest speeds
the laser beam will be focused down, forming a
beam waist as it passes through the modulator.
The first order beam of a modulator is frequency
shifted by the amount of the RF carrier frequency:
it acts like as fixed frequency shifter. By varying
the frequency, you can get a variable frequency shifter.
BDO design: We offer a specific design called BDO
«Beam Drift Optimization» for those applications
which need superior beampointing stability.
