摘要: Optical frequency combs were developed nearly two decades ago to support the world's most precise atomic clocks. Acting as precision optical synthesizers, enable transfer of phase and information from a high-stability reference hundreds thousands tones in domain. This versatility, coupled with near-continuous spectroscopic coverage terahertz extreme ultra-violet, has enabled measurement capabilities both fundamental applied contexts. review takes tutorial approach illustrate how 20 years source development technology facilitated journey lab into field.
