Abstract
A system for protection from light generated by interaction of laser energy with matter is provided. The system, which is designed for use with lasing apparatus having a laser, includes an optical protection device with at least one optical element of a material that transforms between an active state for blocking laser light and an inactive state, where the optical element is transparent. A mechanism for controlling the transformation of the optical element between the inactive and active states, attaches to the optical protection device and the lasing apparatus respectively, and is responsive to the activating and deactivating of the laser, such that when the laser is activated, the control mechanism causes the optical element to transform to the active state and when the laser is deactivated, the control mechanism causes the optical element to transform to the inactive state.
