K2-1000 High Power GHz Dual Comb Femtosecond Laser

K2-1000 High Power GHz Dual Comb Femtosecond Laser

The K2-1000 high-power GHz dual comb femtosecond laser system is an ideal tool for dual comb spectroscopy and ranging. The system generates a pair of mode-locked femtosecond lasers (optical frequency combs) with slightly different pulse repetition rates. In the time domain, optical delay rapidly sweeps through the range of 1 nanosecond at a very high speed. In the frequency domain, the beat frequency between each pair of comb lines is generated through heterodyne detection. Due to the gigahertz repetition rate, the power of each comb line is very high.
Through a novel shared cavity architecture, the K2-1000 high-power GHz dual comb femtosecond laser system can achieve ultra-low noise during free operation. Especially, laser pairs are passively stable, and the intensity, time, and phase noise characteristics between two comb teeth are highly correlated. Due to having only one laser cavity and no high-speed locking electronic components or optical amplification, most of the complexity of traditional dual comb and ASOPS systems is eliminated. At the same time, the K2-1000 high-power GHz dual comb femtosecond laser has a small footprint andexcellent performance.
