摘要
利用自行设计的电子反馈控制线路 ,将半导体激光器频率作线性调谐 ,使激光频率能连续调谐达 6 0GHz而不发生跳模 (modehopping)。利用这种线路量取的锂2S 2P 谱线 (6 70 8nm) ,连超精细结构 (HFS)都能看见。
By changing the temperature of a semiconductor laser linearly and keeping the injection current constant, the frequency of a single mode laser can be continuously scanned up to 60 GHz. The spectrum of 2S 2P resonance transition of lithium, recorded by the method, even some hyperfine structure was clearly resolved.
