AeroDIODE Acousto Optic Modulators are used in laser Q-switching and pulse picking applications, narrow line width laser measurements and many other applications related to precision operating in the nanosecond range.
Acousto Optic Modulators are also used as a fixed frequency shifter. They have the ability to slightly shift the central optical wavelength by a fixed value equal to the RF frequency (±80, ±100 or ±200 MHz) depending on the RF frequency applied to the modulator.
These Acousto Optic Modulators are used as stand-alone products as well as with other products in the AeroDIODE portfolio like :
Acoustic optical modulators are a high performance alternative to other modulator solutions such as Electro-Optic Pockels cells Modulators (offered by companies such as EKSMA Optics or Syndor technologies)
AeroDIODE is a member of EPIC European industry association and “Route des Lasers” cluster .
