Abstract

Recording and detection (reading) of 3D structures in glass using powerful femtosecond laser pulses has been investigated experimentally and theoretically for 3D optical memory applications. Recording of memory 'bits' was found to involve optical breakdown within bulk fused silica leading to plasma formation and strong laser absorption. The measured threshold for in-bulk breakdown of silica of 6×1012 W/cm2 was found to be in a close agreement with the theoretical predictions. As a result of these studies the precise control over the size of the memory bits formed by single and multiple pulses has been achieved.
