Hello, I am interested in modulating a laser beam with a radio frequency. Can I input the signal to the laser, or do I need to modify the beam with something like a heterodyne interferometer. If both approaches would work, would the resulting beam be the same?

Thanks, Bill

It depends on your laser system and how much bandwidth is available to your switching mechanism. An Electro-optic or Acousto-optic switch should have sufficient bandwidth to modulate the laser output at radio frequencies.

What are you modulating- the amplitude, the frequency, the polarization....?
