PHOTOINDUCED BRAGG DIFFRACTIVE STRUCTURES CREATION IN LITHIUM NIOBATE CRYSTAL USING ULTRAVIOLET NANOSECOND EXCIMER PULSE LASER
Read the full article ';
The article deals with holographic Bragg gratings creation method in lithium niobate crystals by excimer laser pulse illumination and the possibility оf its recording in different modes. The main parameters dependencies of obtained phase holographic elements from power and number of pulses are researched.
