Abstract
A system modifies the optical properties of an object by using a light beam from a light source that is focused at a first focal point within the object to optically change a first location within the object at the first focal point. The light beam is focused at a second focal point within the object to optically change a second location within the object at the second focal point. The light beam is focused at a third focal point within the object to optically change a third location within the object at the third focal point The object is moved relative to the light beam while creating the optical change at the second location.

A method of modifying the optical properties of an object comprising:
- (a) focusing a light beam from a light source at a first focal point within said object to optically change a first location within said object at said first focal point;
- (b) focusing said light beam from said light source at a second focal point within said object to optically change a second location within said object at said second focal point, where a first distance is between said first position and said second position, where a first time occurs between optically changing said first location and said second location;
- and
- (c) focusing said light beam from said light source at a third focal point within said object to optically change a third location within said object at said third focal point, and a second distance is between said second position and said third position, where said first distance is different than said second distance, where a second time occurs between optically changing said second location and said third location, and said first time is substantially the same as said second time.
