Laser frequency combs (LFCs) have played a key role in high-precision optical frequency metrology for over a decade and have been used in a variety of applications in fundamental science on the macroscopic scale (e.g. astronomy) and the microscopic scale (e.g. studying optical transitions in atoms). As technology evolves, LFCs become more and more attractive for industrial applications where the main requirements, in addition to high precision measurements, are low-maintenance, long-term stability, flexibility and usability.
Laser Quantum’s solution to the taccor comb is highly suited for both scientific and industrial purposes. The taccor comb preserves the turn-key operation, long-term stability and low-maintenance of Laser Quantum’s successful 1 GHz femtosecond laser taccor and is thus also attractive for users new to the field of LFC applications. The 1 GHz repetition rate is unique to the market and exceeds the performance of LFCs based on lower repetition rate lasers. The taccor comb benefits from over 15 years of experience in high repetition rate femtosecond laser development and has been used to set world records in the field of optical frequency metrology.
