Modulating a laser beam with radio frequency can be achieved through two primary methods: directly inputting the signal to the laser or using a heterodyne interferometer. The choice of method depends on the specific laser system and the bandwidth of the switching mechanism. Electro-optic and Acousto-optic switches are recommended for their sufficient bandwidth to effectively modulate laser output at radio frequencies. The resulting beam characteristics may vary based on the modulation approach used.
PREREQUISITESOptical engineers, physicists, and researchers involved in laser technology and modulation techniques will benefit from this discussion.
Bill E said: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
