the high-finesse cavity can be used to measure the laser linewidth due to its narrower cavity linewidth, with which the linewidth of dbr laser is measured as 1.49mhz 由于高精細度腔窄線寬特點,它可用來測量激光線寬。實驗中用它測量dbr激光器線寬為1.49mhz。
in this thesis, it is mostly showed about the setup and the losses measurement of high-finesse optical cavity, including its application to measuring the linewidth of semiconductor laser . for the example, it is used to measure the linewidth of dbr laser and research the rules of linewidth influence of injected noise on the semiconductor laser 本文主要介紹了高精細度腔的建立及其低損耗的測量,還介紹了其在半導體激光器線寬測量方面的應(yīng)用,例如測量dbr激光器線寬和研究噪聲對半導體激光器線寬的影響規(guī)律。
