Rare-earth-based lasing in multiple bands simultaneously

Researchers successfully demonstrate room-temperature multiband microlasers spanning a large wavelength range using rare earth elements. The lasing process combines downshifting and upconversion, expanding the emission wavelength range. The resulting microlasers exhibit good intensity stability and are suitable for practical applications.

New Super-Pulsed thulium fiber laser improves treatment results in pediatric patients with urinary stones

A new study published in The Journal of Urology found that a super-pulsed thulium fiber laser system improved stone-free rates and reduced residual fragments in pediatric patients with urinary stones compared to standard low-power holmium:yttrium-aluminum-garnet lasers. The study, which evaluated 125 procedures in 109 patients, showed ...

T-rays will 'speed up' computer memory by a factor of 1,000

Scientists have found a way to significantly improve computer performance by using T-waves, or terahertz radiation, to reset memory cells. This process is several thousand times faster than magnetic-field-induced switching and could lead to ultrafast memory.
