- Abstract
- We report on synthesis of compressed silica phase formed inside a α-quartz host crystal using powerful shockwave and thermal transients generated via local optical breakdown induced by low-energy, tightly focused femtosecond laser pulses. Structural characterization of irradiated areas by the X-ray diffraction technique reveals signatures of a new high-pressure phase of silica, which is theoretically expected to form at a pressure of 120 GPa.
