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.
