The key specifications of an AOM driver are:

· Output power: The maximum power that the driver can deliver to the AOM. This determines the maximum intensity of the acoustic wave that can be generated.

· Frequency range: The range of frequencies that the driver can generate. This determines the range of modulation frequencies that can be achieved.

· Rise/fall time: The speed at which the driver can switch between different output levels. This affects the speed of modulation and the ability to generate high-frequency signals.

· Amplitude control: The ability to control the amplitude of the output signal. This determines the depth of modulation of the light beam.

· Phase control: The ability to control the phase of the output signal. This can be used to adjust the timing of the modulation.
