Luminescence Characteristics of Filaments in Lithium Fluoride Crystals
Abstract
The correct conditions for measuring the luminescence intensities in filaments formed by the action of femtosecond laser pulses have been found for lithium fluoride crystals. The conditions determined ensure that the measured intensities are proportional to the concentrations of luminescent color centers created in crystals by laser radiation, and allow conclusions to be drawn about the processes occurring in the filaments. Near-cluster color centers have been found, indicating the presence of nanosized clusters in all areas of the filaments.
