A new type of ultrafast laser technology is being developed to create high-precision microstructures, such as those needed for smartphone displays. The project aims to make the technology cheaper and more efficient, with potential applications in glass processing, polymer ablating, and future laser surgery.
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.
