利用波长为5.2微米的量子级联分布反馈激光器对NO分子的R(13.5)1/2和R(13.5)3/2跃迁进行了Lamb-DIP实验，获得了亚多普勒分辨率受限的饱和特征。凹陷表现为全宽约4.3 MHz的传输尖峰。在此分辨率下，通常被130 MHz多普勒展宽所遮挡的R(13.5)3/2谱线的73 MHz倍增很容易解决。
A quantum cascade distributed feedback laser operating at 5.2 microm is used to obtain sub-Doppler resolution limited saturation features in a Lamb-dip experiment on the R(13.5)1/2 and R(13.5)3/2 transitions of NO. The dips appear as transmission spikes with full widths of ~ 4.3 MHz. At this resolution the 73 MHz _-doubling of the R(13.5)3/2 line, which is normally obscured by the 130 MHz Doppler broadening, is easily resolved.
