But don’t let its size fool you. This tiny laser could power the next generation of self-driving cars, space science tools, and high-precision clocks.

Optical frequency combs are lasers that can act like rulers to measure specific frequencies of light with high accuracy.

Researchers demonstrated a broadband infrared frequency comb that can operate stably, efficiently, and accurately without the need for bulky external components. The device could be utilized in a ...

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 ...

The breakthrough came from probing thorium-229 nuclei with a laser device called a frequency comb. The set-up isn’t technically a clock, because it hasn’t been used to measure time.
