Title: Pierre Brochard: Innovator in Dual-Comb Spectroscopy
Introduction
Pierre Brochard is a notable inventor based in Neuchâtel, Switzerland. He has made significant contributions to the field of spectroscopy, particularly through his innovative work on dual-comb spectrometers. With a total of 3 patents to his name, Brochard continues to push the boundaries of optical technology.
Latest Patents
One of his latest patents involves a dual-comb spectrometer that utilizes two lasers to output respective frequency combs. These lasers have a frequency offset between their intermode beat frequencies, with one laser acting as a master and the other as a follower. The master laser is driven with a nominal DC drive signal, but its current oscillates with an AC component that follows the beating of the intermode comb lines. This AC component is tapped off and mixed with a reference frequency to create the necessary frequency offset. The mixed signal is then supplied to the follower laser, ensuring that the frequency combs are phase-locked relative to each other. This innovative approach allows for frequency stabilization of the electrical signals obtained through multi-heterodyning the two optical signals.
