Abstract
A computer controlled laser apparatus having multiple mirrors positioned along the locus of an ellipse having a first focus point at the center of an angle select mirror and a second focus point on a workpiece to be soldered. Such a geometrical configuration permits a computer to efficiently control the reflection of the laser beam onto the workpiece at different angles of incidence while maintaining a constant laser beam pathlength without requiring refocusing of the beam as it is moved from angle to angle.
