Abstract
A method of generating laser pulses () includes: creating a circulating light field in resonator device () having resonator length L and an intra-cavity dispersion and configured for supporting light field resonator modes, and generating a pulse train of laser pulses () by a mode-locking mechanism. Laser pulses () are generated with a repetition frequency and provide a frequency comb with carrier frequency ωand comb modes in frequency space. The intra-cavity dispersion is selected such that round trip phases ϕ have a dependency on frequency ω according to wherein m is an integer providing effective repetition rate (mω) in combination with mode spacing ωat optical carrier frequency (ω), and the mode-locking mechanism provides a coupling of the resonator modes whereby frequency difference (Δn=ω−ω) between neighboring mode frequencies (ω, ω) is a linear function of mode frequency number n. Furthermore, a spectroscopy method for investigating a sample, a laser pulse source apparatus and a spectroscopy apparatus are described.
