Optics and Acousto Optics / Acousto Optic Devices

Acousto Optic Devices (AOTF)

An acoustic deflector/scanner changes the angle of direction of a laser beam and its angular position is linearly proportional to the acoustic frequency - the higher the frequency, the larger the diffracted angle.

Brimrose offer high resolution UV-VIS-IR deflectors, high speed VIS-NIR deflectors, high bandwidth VIS-IR deflectors, high speed NIR deflectors, multichannel VIS deflectors and variable frequency drivers.

Acousto Optic Components
	Product Type	Description
	AO Tunable Filters	Solid-state electronically tunable spectral bandpass filter, no moving parts, capable of accessing thousands of precise wavelengths in <1s
	AO Modulators	Focusing lens, A-O device positioners and a recollimating lens in an optical module
	AO Frequency Shifters	The diffracted beam of the AOM and AOD is also shifted in frequency (wavelength) by the acoustic beam
	AO Mode Lockers	Use mode-locking or phase-locking process to connect the longitudinal modes by fixing the relative phase differences
	AO Q-Switches	Variable cavity loss laser providing very intense pulse - highest conversion efficiency of RF energy into acoustic energy
	AO Deflectors	Changes the angle of direction of a laser beam
	AO Cavity Dumpers	Dumps laser energy from resonant cavity in form of single optical pulse
