Laboratory Setup LPT-3 “Experimental Electro-Optical Modulation System”

The LPT-3 “Electro-Optical Modulation” experimental system is designed for educational and research laboratories to demonstrate and study the principles of controlling light beams using an electric field. It enables experiments on varying the intensity, phase, and polarization of laser radiation, investigating the response dynamics of electro-optical crystals, and understanding the operation of modulators.

The kit includes a laser source, an electro-optical modulator, optical elements (lenses, mirrors, polarizers), a power supply unit, and multimedia teaching materials. The system is easy to operate, highly illustrative, and ensures precise and stable measurements.

LPT-3 is widely applied in universities, engineering institutions, and scientific centers for student training and applied research in optics and photonics.

Acousto-optic effect refers to the phenomenon of light diffraction in the environment disturbed by ultrasound. This phenomenon is the result of the interaction of light and acoustic waves in the environment. Acousto-optic effect provides effective control of the strength, direction and intensity of laser radiation. Acousto-optic devices created with acousto-optic effect, such as acousto-optic modulator, acousto-optic deflector and tunable filter, have important applications in laser technology, optical signal processing and integrated optical communication technology.
