摘要
实验研究了基于Nd:YVO4晶体的亚太赫兹(sub-THz)双频微片激光器(DFL)的热效应及其对输出激光信号频差的影响。在实验中, 通过改变DFL的温度, 实现了激光信号频差的调谐。实验结果表明, 在一定温度范围内, DFL的激光信号频差随激光器温度的升高呈线性增长, 以此可实现频差的温度调谐。
Abstract
The thermal effect of sub-THz microchip dual frequency lasers (DFL) based on Nd:YVO4 crystals and its influence on the frequency difference of laser output signals are experimentally studied. In the experiment, the frequency difference tuning of laser signals is realized by tuning the DFL temperature. The experimental results indicate that, within a certain temperature range, the frequency difference of DFL signals linearly increases with the increment of temperature. Based on this point, one can realize the temperature tuning of frequency difference.
