| titleOfInvention | Alleviation Of Laser-Induced Damage In Optical Materials By Suppression Of Transient Color Centers Formation And Control Of Phonon Population |
| abstract | Laser-induced damage in an optical material can be mitigated by creating conditions at which light absorption is minimized. Specifically, electrons populating defect energy levels of a band gap in an optical material can be promoted to the conduction band—a process commonly referred to as bleaching. Such bleaching can be accomplished using a predetermined wavelength that ensures minimum energy deposition into the material, ideally promoting electron to just inside the conduction band. In some cases phonon (i.e. thermal) excitation can also be used to achieve higher depopulation rates. In one embodiment, a bleaching light beam having a wavelength longer than that of the laser beam can be combined with the laser beam to depopulate the defect energy levels in the band gap. The bleaching light beam can be propagated in the same direction or intersect the laser beam. |
