Abstract
A multiple frequency comb source apparatus () for simultaneously creating a first laser pulse sequence representing a first frequency comb () and at least one further laser pulse sequence representing at least one further frequency comb (), wherein at least two of the first and at least one further pulse sequences have different repetition frequencies, comprises a laser resonator device () comprising multiple resonator mirrors including first end mirrors EM,OCproviding a first laser resonator (), a laser gain medium () being arranged in the laser resonator device (), and a pump device () being arranged for pumping the laser gain medium (), wherein the laser resonator device () is configured for creating the first and at least one further laser pulse sequences by pumping and passively mode-locking the laser gain medium (), the resonator mirrors of the laser resonator device () include further end mirrors EM, OCproviding at least one further laser resonator (), the first laser resonator () and the at least one further laser resonator () share the laser gain medium (), resonator modes of the first laser resonator () and the at least one further laser resonator () are displaced relative to each other, wherein the resonator modes are located in the laser gain medium () at separate beam path spots, and at least one of the first and further end mirrors EM, EM, OC, OCis adjustable so that the repetition frequency of at least one of the first and at least one further laser pulse sequences can be set independently from the repetition frequency of the other one of the first and at least one further laser pulse sequences. Furthermore, a spectroscopic measuring method, a spectroscopy apparatus and a multiple frequency comb generation method are described.
