摘要

设计了一种基于LabVIEW控制的自动宽调谐的连续单频钛宝石激光器, 通过波长计测量激光器输出波长, 用LabVIEW程序读取该波长值并产生控制信号, 反馈控制腔内调谐元件双折射滤波片(BRF)的角度, 实现对激光器输出波长的调谐。此外, 基于波长计测量的系列波长值, 构建了BRF角度与激光器输出波长值的一一对应关系, 由LabVIEW程序根据不同的波长设定值控制BRF旋转不同的角度, 使钛宝石激光器不需要波长计也能实现自动调谐, 简化了激光器系统。对实验设计的钛宝石激光器进行自动调谐, 测量得到其调谐范围为110 nm。

Abstract

An automatically and broadly tunable Ti∶sapphire laser based on the control of LabVIEW is designed, which is implemented by feedback controlling the angle of intracavity birefringent filters (BRF). The feedback signal is generated by LabVIEW program after the laser output wavelength measured by a wavelength meter is obtained. Then the one-to-one relationship between the BRF angle and the laser output wavelength is established based on the measured wavelengths. The BRF angle corresponding to the setting wavelength is calculated and then controlled by LabVIEW procedure, so that the laser wavelength can be automatically tuned without wavelength meter, which simplifies the laser system. With the automatically tunable system, the tuning range of the designed Ti∶sapphire laser is 110 nm.
