Abstract
A laser beam generating device includes a housing a first laser diode which generates a visible first output beam which projects outside of the housing onto a surface and a second laser diode which generates a visible second output beam which projects outside of the housing onto the surface. The laser beam generating device has a first mode in which the first laser diode and the second laser diode are both on. In the first mode, the first laser diode is operated at a first duty cycle the second laser diode is operated at a second duty cycle. The first duty cycle and the second duty cycle are staggered.
