Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across ...

MOST is unlike any spectroscope ever built. It can unravel the light of 2,400 celestial objects simultaneously into 18,000 color components.

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
