Abstract
Laser systems are provided with a semiconductor laser having an emission face, a drive circuit adapted to supply electric energy to the semiconductor laser to cause the semiconductor laser to emit a beam; a user input system adapted to sense a user input action; a controller adapted to control the drive circuit based upon the sensed user input action; a housing within which the laser is positioned and having an opening with a window through which the semiconductor laser can emit the beam. The semiconductor laser is positioned to emit the beam through the window and the emission face of the semiconductor laser is sized to cause a divergence in the beam to create a patterned emission with a predetermined shape without passing the beam through beam shaping optics.
