Horizontal laser rays generated by the two laser modules intersect with each other, so as to form laser rays with a diffusion angle of 360 degrees.

Consequently, the intensities of the laser beams are not decrease when the laser beams reach the double-refraction element, and thus a high-output semiconductor laser module is provided.

The laser propagates laser radiation toward the plate which is incident on the plate at a second incidence angle.

Beams are bundled by means of the objective, said beams not only containing the laser beams (3) reflected on the objects but also background beams (28).

The device comprises means (1) arranged to emit laser radiation and modulating means (2) arranged in the beam path between the laser-radiation-emitting means (1) and the eye (5) so as to modulate the laser radiation.

system of cylinder-making using laser engraving

The invention relates to an apparatus for protection against laser beams.

The read and write laser beams can be orthogonally polarized.

Disclosed is a device for treating a substrate with laser radiation, wherein the incoming laser rays can be directed in such a way as to form various outgoing beams.

Green lasers are x 4 time more visible to the human eye than red lasers of the same output power.

The invention further includes a mechanism (102) for aligning the laser beams.

The receiver (14) registers the break in the laser beam (16) and activates an alarm.

The invention is directed to conversion of typical profile laser beams into profile beams by non-linear optical systems.

A fiber bundle (12) including a plurality of parallel optical fibers (11) receives source laser rays at one end and provides output laser rays (24) at the other end.

The laser radiation modifies the bioactive substance to thereby modify reactions relating thereto in the body.
