Research on driving power supply for high-power and broad tuning acousto-optic modulator
摘要
Abstract
Acousto-optic modulator is an important optical device,and its performance largely depends on the quality of driving power supply.Therefore,it is of great significance to develop high performance acousto-optic modulator driving power supply for different application scenarios.In order to meet the application requirement of optical parametric oscillation cavity length locking for acousto-optic modulator in vacuum squeezed light preparation in quantum optics,a high-performance acousto-optic modulator driving power supply is designed in this work.In this driving supply,the radio frequency metal-oxide-semiconductor field-effect transistor(RF MOSFET)amplifier module RA07H0608M is proposed as the core device,and the input signal is finally injected into acousto-optic modulator after passing through impedance matching circuit,high-pass filtering amplifier circuit and power amplification circuit.At the same time,the monitoring circuit monitors the working temperature and signal power in real time.The results show that the acousto-optic modulator driving supply can achieve continuous frequency and power tuning.In the operating frequency range of 75-85 MHz,the input and output signals have a good linear relationship,the output power is up to 1 W,and automatic shutdown protection of over-temperature and over-power can be achieved.It is indicated that the designed driving power supply can fully meet the requirements of long-term stable operation of acousto-optic modulator.关键词
