Quartz crystal, e.g. piezoelectric or optical component, has modified crystal lattice structure obtained by removing desired quantity of quartz using focused laser beam

摘要

A desired geometric interstitial variation in a quartz crystal is produced by using specialized photon laser or atom laser machining to permanently modify the optical and electrical resonance properties. Preferably the desired amount of quartz material is removed by partial or complete perforation using laser machining. The focussed laser beam may be used to produce 2D or 3D forms exhibiting new optical properties.
