Caption: This colorful apparatus is a key part of the JILA frequency comb instrument used to measure trace gases for biomedical applications. The beam from a powerful fiber laser is converted by a special crystal and other optics into two light waves at lower frequencies. The system can detect and measure the concentration of many different molecules based on how they absorb light in the mid-infrared region of the electromagnetic spectrum.
Usage Restrictions: None
