Uv-visible Lasers Based on Rare-Earth Lons

摘要

It is evident that the expansion of rare- earth-doped solid-state lasers into new wavelength regions is proceeding in sev- eral ways, as is appropriate, since a range of potential applications exists. These in- clude detection of polutants and biologi- cal hazards in the pollutants and biologi- cal hazards in the atmosphere using UV lasers, submarine communications with blue light, photolithography, color dis- plays, biotechnologies such as ophthal- mology in the UV, deposition of thin films using UV light, and high-density optical information storage.
