【摘要】：將自由運轉(zhuǎn)的激光器參考鎖定在隔振、恒溫、高細度的Fabry-Pérot(F-P)參考腔上,獲得了短期穩(wěn)定性頻率較好的窄線寬激光。為了降低溫度對激光頻率穩(wěn)定性的影響,F-P腔的腔體一般選用具有超低熱膨脹(ULE)系數(shù)的玻璃材料。ULE玻璃存在一個特定的溫度點,該溫度點下其ULE系數(shù)接近0,稱之為拐點溫度。由于其拐點溫度通常低于或者高于室溫,因此設(shè)計了一套主動溫控裝置,該裝置可在高真空環(huán)境中將F-P腔的溫度控制在-5~40℃范圍內(nèi),并且一天內(nèi)F-P腔的溫度波動范圍在±0.005℃以內(nèi)。該溫度控制裝置可應用在工作波長為729nm的ULE F-P腔系統(tǒng)中,當該參考腔的溫度控制在拐點溫度(17.3℃)附近時,平均線性頻率漂移控制在100mHz/s以內(nèi)。
[Abstract]:The reference of the free-running laser is locked on the Fabry-P 茅 rott F-P reference cavity with vibration isolation, constant temperature and high fineness, and a narrow linewidth laser with good short term stability frequency is obtained. In order to reduce the influence of temperature on laser frequency stability, the cavity of F-P cavity is usually composed of glass material with ultralow thermal expansion coefficient. There exists a specific temperature point for the glass. The ULE coefficient is close to 0 at this temperature point, which is called inflection point temperature. Since the inflexion temperature is usually lower or higher than room temperature, an active temperature control device is designed, which can control the temperature of F-P cavity within -5 ~ 40 鈩，
