Cambridge, MA – Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

Expert sommeliers can take a whiff of a glass of wine and tell you a lot about what's in your pinot noir or cabernet ...

A new chip with hundreds of microscopic rings generated the first topological frequency comb. Credit: E. Edwards Scientists on the hunt for compact and robust sources of multicolored laser light have ...

Ultrabroadband IR frequency comb could be used for detection in portable spectrometers. The comb uses a double-chirped mirror. Researchers at MIT have demonstrated a compact, fully integrated ...

David, Nate, and Prof. Rieker travel to JPL in Pasadena to work on their latest high temperature absorption spectroscopy data. Anthony Torres and Prof. Rieker head to AIAA Scitech, where Anthony ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...
