Dual-Comb Spectroscopy

Takuro Ideguchi

Using paired coherent frequency combs for broadband molecular spectroscopy can provide dramatic gains in spectral resolution, sensitivity and data acquisition speed—and may help take the power of frequency comb spectroscopy out of the lab and into the field.


Pairing objects can bring new functionality. A pair of chopsticks easily feeds us, while a single one would be useless. A pair of eyes lets us visualize the world in 3-D, rather than the flat, 2-D view we would have with only one.
