Optical frequency combs are breaking new ground in applications ranging from precision timing to breath analysis. Marie Freebody speaks to Jun Ye from JILA to find out more. Jun Ye is a fellow of JILA ...

(Nanowerk News) Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength.

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

Researchers at Lawrence Livermore National Laboratory (LLNL) have optimized and 3D-printed helix structures as optical ...

Using nonlinear crystals to convert the frequency of a laser gets a new look as an Italian researcher unveils a 3/2 frequency multiplier that could simplify RGB laser systems. Multiplying the ...

Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum. The electromagnetic spectrum is a continuous range of wavelengths. The types of ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
