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.

Laser line generating device

A laser beam generating device is provided for generating multiple mutually orthogonal light beams. The device includes a laser light generator that generates at least three output beams. A beamsplitter of the laser light generator has two incident surfaces orientated at forty-five degrees in relation to an optical axis. A first portion of a light from a light source is incident on a first of the two incident surfaces and output as a first output beam in a first direction orthogonal to the optical axis. A second portion of the light is incident on a second of the two incident surfaces and output as a second output beam in a second direction opposite the first direction. The light source is arranged in relation to the beamsplitter such that a third portion of the light bypasses the beamsplitter and forms a third output beam projected parallel to the optical axis.

An improved laser line generating device is provided for use in construction layout tasks. The laser line generating device is comprised of a first laser light generator operable to emit from a housing a first plane of light having a fan angle greater than 180&#xb0; and arranged in the housing to project the first plane of light perpendicular to a horizontal plane; and a second laser light generator operable to emit from the housing a second plane of light having a fan angle greater than 180&#xb0; and arranged in the housing to project the second plane of light perpendicular to the first plane of light and perpendicular to the horizontal plane, such that the first plane of light intersects with the second plane of light at two points.
