taccor comb

Specification / Features / Downloads

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 40 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 or taccor ultra.

Central Wavelength800 nm (+/- 20nm) Laser ClassClass IV


The comb extension can be used in combination with the taccor power or taccor ultra lasers with the taccor power offering up to 1 W of useable 800 nm available after the CEO frequency measurement. When combined with the taccor ultra 8 or 10, the system delivers up to 800 mW of output power with 15 fs pulse duration.
