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.
