F-SG1080 Acousto-optic Effect of Crystal Experiment contents and related subjects: 1.Observe the diffraction phenomenon of ultrasonic grating in crystal and measure the diffraction efficiency. 2. Understand the interaction mechanism between sound waves and light wavee and project the sound velocity in materials. 3.Modulation, transmission and demodulation of the analog signal (audio) . 4.The relationship between modulating frequency and driving frequency (specific annexes are needed). Features of the instruments: 1.Gold plating technology is used in quartz crystal electrode and also be connected with heavy flint glass indium solder to make the coupling more reliable and effective. And, also, the experimental results will be better. 2.Sound wave frequency of the acousto-optic modulator(AOM) drive power is 9-11MHz. 3.12 steps light probe combined with an one-dimensional displacement planes are adopted to measure the intensity distribution: the accuracy of lateral movement is 0.02mm. Complete set of equipment: Optical experiment guide, semiconductor lasers, acousto-optic crystal + one-dimensional slider, big one-dimensional displacement planes + 12 steps light probe, drive power of acousto-optic modulator, lens, laser power indicator and other equipments
