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.

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.
