Fourier domain mode locking
text:
Fourier domain mode locking (FDML) is a laser modelocking technique that creates a continuous wave, wavelength-swept light output. A Fourier domain mode locked laser consists of a ring cavity of length L with tunable optical bandpass filter and gain element. For FDML operation, the filter tuning frequency f needs to match the inverse cavity roundtrip time 1 / τ = c / or a ith harmonic thereof, with the group speed of light c / n in the fiber cavity, where c is the speed of light in vacuum and n
