摘要
使用STM32F103ZET6单片机控制, 采用PA92功率放大器驱动压电陶瓷, 设计了532nm平平腔结构的F-P扫描干涉仪。腔镜反射率为99%, 精细度310, 腔长0.1~150mm连续可调, 对应自由光谱区1~1500GHz和分辨率3.2~4800MHz连续可调。压电陶瓷驱动电压和频率通过编码器调节, 可以在0~200V和1~100Hz连续可调, 并显示在数码管上。同时可以通过RS232串口与计算机通讯, 在上位机使用LabVIEW软件界面方便地设置压电陶瓷驱动电压和频率。使用F-P扫描干涉仪, 对激光二极管泵浦Nd∶YVO4/KTP绿光激光器纵模进行了测量, 验证了整个系统的工作性能稳定可靠。
Abstract
A planar-planar 532nm F-P scanning interferometer is designed based on STM32F103ZET6 single-chip microcomputer and PA92 power amplifier. The principle is analyzed using MATLAB software. PA92 power amplifier is used to drive PZT. The reflectivity of the mirror is 99%, corresponding to the fineness of 310. The length of the cavity can be adjusted continuously and is set to be 0.1~150mm, corresponding to the free spectrum of 1~1500GHz and resolution of 3.2~4800MHz. The voltage and frequency of the PZT can also be adjusted continuously by encoder setting to be 0~200V and 1~100Hz which are displayed on the LED digital tube. The PZT driver can communicate with computer by RS232 serial port, and the voltage and frequency of the PZT can also be adjusted continuously by LabVIEW software. The longitudinal mode of a diode-pumped Nd∶YVO4/KTP green laser is inspected. The system working well is verified.
