THz頻率量度之先導研究 一對半導體雷射與飛秒光頻梳之鎖相研究

Abstract

我們實現半導體雷射與飛秒鎖模雷射的互鎖。利用半導體雷射與飛秒雷射光梳頻的拍頻，半導體雷射頻率可以被鎖定在飛秒鎖模雷射的光梳頻上。在論文中利用脈衝雷射的光梳頻訊號來作為半導體雷射的頻率標準，並完成半導體雷射的穩頻，使得原本100MHz的頻率擾動降至1MHz ~5MHz，並將半導體雷射光頻率鎖定在358660.800GHz。

We characterize the phase locking between CW semiconductor laser and mode-locked pulse laser. Through beating signal between CW diode laser and mode-locked pulse laser, semiconductor laser could be locked to the harmonic frequency of repetition rate of mode locked laser. In this thesis, we use the harmonic frequency of mode-locked laser as the standard of dual-wavelength CW semiconductor laser and stabilize the frequency of laser diode .We depress the frequency fluctuation of laser diode from 100MHz to 1~5MHz and lock the frequency of CW diode laser to 358660.800GHz.
