Laser technology
Acousto-optic modulators allow laser pulses to be managed precisely and in short bursts, creating ultrafast optical signals with short wavelengths. They can also generate optical holograms and acoustically lensed lasers.
Lasers work by recombining electrons and holes generated by power sources in an electrically-pumped semiconductor diode. This results in photon emission which rebounds off mirrors on either side of the semiconductor to form near exact copies on either side.
The intensity of a diffracted beam depends on acoustic power, and can be altered by altering voltage applied to the piezoelectric transducer bonded to a crystal. This feature allows acousto-optic devices to act as pulse pickers and fast switches; additionally they are often found used as Q-switches, mode lockers and cavity dumpers in pulsed laser systems, as well as fixed and variable frequency shifters.

Optics
Acousto-optic devices market is driven by several growth drivers. One such factor is rising demand for laser treatments in healthcare such as LASIK surgery and hair removal; another key driver of growth for these technologies is increased adoption of telemedicine/remote medicine technology.
Acousto-optic modulators and tunable filters are used to manage electromagnetic radiation’s intensity, frequency, state of polarization and state of polarization. To function properly these devices require various acousto-optic (AO) materials that vary depending on laser parameters.
Effective acousto-optic devices rely on interaction length between light and sound waves; shorter interaction length means wider modulation bandwidth. Fused silica, lithium niobate, tellurium dioxide and indium phosphide are among the more commonly used materials; they offer high frequencies, power densities and can accommodate complex optical designs like real-time ambiguity functions.

Sound waves
Sound waves are vibrations that move through air or water and cause particles to vibrate back and forth, creating high-pressure regions (compressions) and low-pressure regions (rarefactions) with periods between them known as wavelengths separating each compression and rarefaction; only those frequencies within human auditory range result in detectable hearing sensation.
Using an acousto-optic deflector, researchers can rapidly steer and focus the laser beam used in two-photon microscopy, enabling ultrafast random-access scanning and providing greater insights into neural processing of sensory information in the brain.
An Acoustic Opto-Optic Tunable Filter (AOTF) works by applying a radio frequency electric signal to a piezoelectric transducer attached to a crystal of tellurium oxide. The vibrations caused by this RF signal cause its crystal to vibrate, producing bands of compressed and expanded material similar to what would be found in a diffraction grating diffraction gratings; with different excitation signals available it becomes possible to switch frequencies thereby making an AOTF an adjustable frequency shifter!

Light waves
Light waves manipulated by acousto-optic devices can be harnessed for many different applications, with one of the most popular ones being acousto-optic spectral imaging. An AOTF is one of the key components of this type of device and can be found in a variety of optical systems – the input light can either be polarized or unpolarized; when placed inside an AOTF it scatters unpolarized light into two orthogonally polarized output beams which overlap each other by small amounts before dispersion sets it off completely.
The Acoustic Wave Tuning Facility (AOTF) makes use of a birefringent crystal that alters its optical properties upon interaction with an acoustic wave, enabling rapid wavelength tuning through rapid transmission times in a crystal. A variety of acousto-optic materials, such as tellurium dioxide and quartz can be utilized, along with gallium niobate or lithium niobate glasses to achieve this end.

Modulation
Acousto-optic devices have become increasingly popular due to advances in crystal growth and piezoelectric transducers, with applications for deflecting, modulating, signal processing and frequency shifting of light beams becoming the focus of interest.
Operationally, acousto-optic (AO) tunable filters use Fourier mode coupling theory for their operation. When coupled with nonuniform fiber Bragg grating-based AO filters, their diffracted light wavelength corresponds directly with its respective acoustic frequency – determined by l displaystyle lambda/v where v is the acoustic velocity and n displaystyle n_d is its refractive index of crystal.
Performance of acousto-optic tunable filters is usually determined by their material’s figure of merit; common examples include fused quartz, tellurium dioxide and lithium niobate as these offer excellent balance among optical transmission, attenuation and power density.

Diffraction
Acousto-optic devices harness the interaction between light and acoustic waves to manipulate optical beams by modulating intensity, frequency, polarization and polarization. These devices are used widely across optical systems including Q-switches, mode lockers and spectrometers.
Acoustic-optic (AO) devices can be integrated on a single chip for greater efficiency compared to their bulk counterparts; however, their high initial costs pose as one of the key impediments to growth in this market.
AO devices rely on Brillouin scattering, which occurs when light is scattered by acoustic waves. As these waves travel through material, their vibration causes its refractive index to change in proportion with strain caused by them, enabling you to control intensity or even direction of an optical beam – something useful in applications like diffraction.

Frequency shifting
Researchers have developed a thin-film lithium niobate acousto-optic frequency shifter (AOFS), capable of modulating the optical frequency of an incident light beam effectively. A typical device works when input light interacts with traveling acoustic waves generated by interdigital transducers to produce deflected light that has energy and momentum matching conditions before being coupled into an optical waveguide.
Acoustic waves create strain in materials, which causes changes to its optical refractive index and allows acousto-optic devices to manipulate photons by altering its optical refractive index and thus change photon behavior by deflecting, modulating, shifting or rotating an optical beam’s polarization.
Acousto-optic modulators can be utilized for many different uses, including backward stimulated Brillouin scattering compression and heterodyne interference detection. Furthermore, they serve as an efficient way of measuring temperature and axial strain.
