| 摘 要： | 采用较强的外注入光锁定FP激光器，获得了理想的强度噪声抑制效果. 在自由运转的FP激光器的弛豫振荡峰处，最大噪声抑制强度可达9dB. 研究了注入光功率和频率失谐对于强度噪声抑制效果的影响. 此外，通过实验研究了理想噪声抑制范围与激光器稳定锁定范围之间的关系：它们都随着注入光功率的增加而增大；但在相同的注入光功率下，稳定锁定范围允许更大的频率失谐.

| Abstract: | The optimal intensity noise suppression of a Fabry-Perot (FP) laser is experimentally acquired by relatively strong external optical injection locking technology.The maximum suppression is up to 9dB around the relaxation oscillation peak of the free running FP laser.We demonstrate how the injection light power and detuning frequency influence the intensity noise suppression effects.Additionally,the relationship between the optimal suppression range and the stable locking range is experimentally studied:both ranges enlarge as the injection light power increases,but the stable locking range permits larger detuning frequency at identical injection light power. |
