The taccor comb consists of a powerful 1 GHz turn-key Ti:sapphire laser with a matched dispersion compensation module, super-continuum generation and ultra-stable f-to-2f interferometer. It provides an electrical output signal at the carrier-envelope offset (CEO) frequency with at least 35 dB signal-to-noise ratio in 100 kHz bandwidth. The super-continuum generation fibre coupling is stable for long periods and any long-term variations can be compensated with piezo actuators, controlled via a touch-screen interface. The comb extension can be used in conjunction with the taccor power.

System layout:

The standard configuration of the taccor comb comes with the comb extension module housing the f-2f interferometer and dispersion compensation mirrors.

The remaining output of the 800 nm taccor output beam that is not required for fCEO detection is made accessible to the user via the output aperture as free space coupled beam. The beam exhibits average powers of up to 1 W (600 mW with the taccor power 6).

With the option “Supercontinuum output” a second module is added consuming the residual 1 W output power. The additional module is equipped with up to two photonic crystal fibres generating a supercontinuum covering the range 520 – 1200 nm with an average power of up to 200 mW after each fibre stage. The output is made accessible to the user at two FC/PC output ports.
