Chinese scientists have pushed solid-state vacuum ultraviolet laser technology to a new milestone by ...

(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.

Under these conditions we observe the emission of strong XUV harmonics. Their spectral content is characterized by a spectrometer after blocking the diverging optical beam with thin aluminum filters ...

A genetic duplication which involves almost one-third of the chromosome has been described in the bacterium Salmonella typhimurium. This duplication occurs at a spontaneous frequency of approximately ...

The new approach produces extremely accurate and stable frequencies and could significantly enhance precision timekeeping and high-resolution atomic and molecular spectroscopy. WASHINGTON — ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

A 250 mW UV source developed by US researchers could suit quantum cryptography, spectroscopy or micromachining. A team from MIT, Wright-Patterson Air Force Base and AdvR has demonstrated a narrowband ...

Short duration, intense pulses of light can experience dramatic spectral broadening when propagating through lengths of optical fibre. This continuum generation process is caused by a combination of ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for deciphering the properties of light and matter that can simultaneously detect and ...
