摘要：激光器在工作过程中会受到环境温度的变动，机械的振动、磁场效应等的影响，以及自身因素的影响，输出激光的频率会经常随时间变动。而在许多应用中，例如精密干涉测量，光频标，激光通信，激光陀螺等领域，要求激光输出频率具有高稳定性。所以对激光器的稳频技术的研究是很重要的。39803

Semiconductor laser frequency stabilization technology and mechanism research
Abstract: The output frequency of lasers can be disturbed by working temperature fluctuation, mechanical vibration, magnetic field effect and other effects; it also can be changed by the influence of its own factors. In many applications, such as precision interferometry, optical frequency standard, laser communications, laser gyro and other fields, high stability of laser output frequency is required. So it is meaningful to study the laser frequency stabilization.
    In this paper, the research progress of the stability frequency technology for the semiconductor laser is firstly introduced in chapter 1, and the significance of the study is also presented. The second chapter introduces the development history of semiconductor lasers. In the third chapter, the conditions and working mechanism of  semiconductor lasers are explained, and the classification application is described. The fourth chapter is the focus of this thesis, detailed analysis of the various factors that influence the frequency stability of the laser; mainly on active steady frequency technology within the scope of some laser frequency stabilization technology are analyzed. The fifth chapter according to the domestic and foreign about the active frequency stabilization technology research report, the advantages and disadvantages of comparative analysis, and through the review of the literature. Finally, it puts forward a way to begin the study about offset frequency locking technique.
