Acousto-optic modulator - Wikipedia
An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves …
Acousto-optic modulators (AOMs) are useful devices which allow the fre-quency, intensity and direction of a laser beam to be modulated. Within these devices incoming light Bragg di racts o …
acousto-optic modulators – AOM, Bragg cells, diffraction …
An acousto-optic modulator (AOM) is a device which can be used for controlling the transmitted power of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, …
We will implement a technique to modelock a long cavity Helium-Neon laser by injecting frequency shifted light from each longitudinal mode of the laser into an adjacent mode. …
2019年10月30日 · The dashed dependence is the angle of the exact Bragg synchronism, when the wave vector of sound in a single Central point “is in contact” with the wave surface of the …
When the strain is generated by an acoustic compression or rarefaction, an AOM is formed. Because the acoustic signal is sinusoidal, a moving refractive index grating is formed in the …
Angles The input Bragg angle is given by: This angle is in the plane of deflection and relative to a normal from the input optical surface. Except for certain AO devices with birefringent crystals, …
2018年5月3日 · An acousto-optic modulator (AOM) is an optical el-ement that modulates the frequency of light by an ap-plied signal, usually in the RF range. The modulation is a result of …
Thermal Analysis of Acousto-Optic Modulators and Its Influence
2024年11月15日 · Acousto-optic modulators (AOMs) have been widely used in ultra-stable lasers (USLs) for optimizing its performances. A thermal theoretical model of the AOM, which is …
