Research of high speed and high precision LiDAR with real time air refractive index self correction

一个相干合成的双色电光梳在今年内建成。具有不同中心波长的两个CW激光器由EO调制器调制，从而产生两个EO梳。两个电光梳之间的相干合成导致相干合成的双色电光梳的产生，这种相干合成的双色电光梳显示出宽带频谱和低相位噪声的优点。

A coherently synthesized two-color EO comb is constructed within this year. Two CW lasers with distinct center wavelengths are modulated by EO modulators, resulting in two EO combs. The coherent synthesis between the two EO combs leads to the generation of coherently synthesized two-color EO comb. This coherently synthesized two-color EO comb shows the advantageous of broadband spectrum and low phase noise.
