Title: Frequency Comb
Description: Stack of quartz optical 'cavities' -- precisely machined disks of solid quartz crystal -- for use in NIST's compact laser frequency comb. (Only one is actually used.) A low-power infrared laser produces light that travels in a loop inside one of the cavities. Each cavity is 2 millimeters wide and shaped like a flat ellipse.
