Abstract
A method of laser machining a fluid path is provided. The method comprises directing a first laser toward a first surface, directing a second laser toward a second surface of the substrate, and directing a third laser toward the second surface along at least a portion of an edge of an area that defines a portion of the fluid path on the second surface.

A method of laser machining a fluid path comprising:
- directing a first laser toward a first surface of a substrate to form a fluid path through the substrate,
- directing a second laser toward a second surface of the substrate to form the fluid path through the substrate;
- and
- directing a third laser toward the second surface along at least a portion of an edge of an area that defines a portion of the fluid path on the second surface.
The method of claim further comprising directing a fourth laser toward the fourth surface along at least a portion of an edge of an area that defines a portion of the fluid path on the first surface.
A method of defining a fluid path comprising:
- creating a profile for a fluid path through a surface of a substrate, the profile including an edge;
- and
- directing a laser along at least a portion of edge.
A system for defining a fluid path through a substrate, the fluid path being defined at least in part in a first surface of the substrate the system comprising:
- a laser source that defines the fluid path in the first surface;
- and
- means for directing the laser source along the edge after defining the fluid path in the first surface.
A computer readable medium including instruction for operating a computer that controls a laser source, the instructions comprising:
- instructions for directing a laser from the laser source toward a surface of a substrate to form the fluid path through the substrate;
- and
- instructions for directing another laser from the laser source toward the surface along at least a portion of an edge of an area that defines a portion of the fluid path on the surface.
