In a groundbreaking study, researchers have demonstrated how to make optical frequency comb lasers more sensitive by using quantum squeezing. This technique can double the speed of gas detectors, making them faster and more accurate.
Optical frequency combs are lasers that emit light in a wide range of frequencies. They are used in a variety of applications, including gas sensing, telecommunications, and astronomy. However, the sensitivity of these lasers is limited by the noise in the light they emit.
Quantum squeezing is a technique that can reduce the noise in a laser beam. It works by manipulating the properties of the light’s photons. In the new study, the researchers used quantum squeezing to manipulate the light emitted by an optical frequency comb laser.
The result was a laser that was twice as sensitive as a conventional laser. This means that the laser could detect much smaller amounts of gas.
The researchers believe that their new technique could have a significant impact on a variety of applications. For example, it could be used to develop more sensitive gas sensors for environmental monitoring and medical diagnostics. It could also be used to improve the performance of optical communication systems.
In addition to the benefits mentioned in the original article, quantum squeezing can also be used to improve the accuracy of optical clocks. This is because quantum squeezing can reduce the uncertainty in the frequency of a laser.
The researchers believe that their new technique is just the beginning. They are now working to develop even more sensitive quantum-squeezed lasers.
Overall, the new study is a breakthrough in quantum optics. It has the potential to revolutionize a variety of applications, including gas sensing, telecommunications, and astronomy.
