Keely Portway finds out how advances in dual-frequency comb spectroscopy could help to significantly speed-up the rate of detection in a wide range of applications
Dual-frequency comb spectroscopy permits broadband precision spectroscopic measurements with short acquisition time. A dramatic improvement of the maximal spectral bandwidth and the minimal measurement time can be expected when the lasers’ pulse repetition rate is increased, owing to a quadratic dependence (Nyquist criterion). This white paper demonstrates a dual-comb system operating at a high repetition rate of 1 GHz based on mature, digitally-controlled, low-noise modelocked lasers
Monitoring greenhouse gases directly from space is essential to improve the accuracy of climate change analysis. This whitepaper details the use of a LIDAR in space using a GHz frequency-comb for in-orbit calibration.
Menhir Photonics offers industrial-grade femtosecond lasers operating at 1,550nm with GHz repetition-rates and ultra-low noise performance. Combined with their unprecedented reliability, these laser enable applications both in the field and in industrial environments. An ultrafast laser that’s as precise and reliable as a Swiss timepiece.
