laserfrekvenskammare
Laserfrekvenskammare are optical devices used to generate a comb-like spectrum of equally spaced laser frequencies. This "frequency comb" is analogous to a ruler for light, with precisely defined and known frequency markers. The core principle behind their operation involves nonlinear optical processes, typically within an optical fiber or a microresonator. A continuous-wave laser is injected into a nonlinear medium, leading to the generation of new optical frequencies through processes like self-phase modulation.
The resulting output is a spectrum consisting of a series of sharp peaks, each separated by a
