Abstract

The early stage of optical damae caused by F₂ laser irradiation on the wide bandgap fluoride crystal, CaF₂, is investigated and compared with the case of ArF laser irradiation. Besides a blue emission band due to self-trapped exciton, sharp emission lines appear and grow at a fluence of about 2 J cm^-2, showing the initiation of the optical damage and growth of plume from the F₂-laser-irradiated surface of CaF₂. There exist cracks and melted structures on the laser-damaged surface, which are caused by thermal stress and vaporization due to laser absorption and following local heating.
