A real optical frequency comb spans the entire visible spectrum of light, and has very fine, evenly spacedteeth.
实际光学频率梳横跨整个可见光谱，各齿极细并均匀分布。

Special crystals, mirrors, and other techniques also are used to make the light waves and comb teeth as perfectly spaced as possible.
为了使光波和梳齿尽可能的完美，特殊晶体和镜面等其它一些技术也得到了采用。

The frequency comb is generated by a laser that produces a series of veryshort, equally spaced pulses of light (like the teeth of a comb) across a broadspectrum of frequencies.
