Fiber coupled acousto optic aom modulator

There are 2 kinds of acousto optic modulators(fiber coupled aom), one is fiber coupled acousto optic modulator, the other is free space acousto optic modulator. Acousto-optic Modulator IR AOM is for IR lasers, such as 1064nm, 1550nm, and 2000nm . More about acousto optic aom modulator.

Acousto-Optic Tunable Filter AOTF

Acousto-Optic Tunable Filter AOTF Operation Principle The basic operation principle is explained in the following. If a sinusoidal (fixed-frequency) RF input signal is applied to the modulator, diffraction is possible only in a narrow range of optical frequencies, where a phase matching condition involving both optical and acoustic waves is fulfilled. Looking at the diffracted […]
