A portable laser marking device for permanently marking objects. The portable laser marking device has a control cabinet including a laser generating unit and an optical fiber that delivers the laser beam from the generating unit to a laser marking head. The laser marking head includes a focusing support with three prongs to keep the surface of the object at a focus distance from the marking head. A handle with marking on/off control is also attached to the laser marking head.

Device and method for laser marking

The invention provides a method for performing interference measurements by observation of interference noise, including the steps of splitting an energy beam from an energy source into two beams directed into two different arms of an interferometer; using variable delay-generating means to introduce a path difference between the two arms; introducing a variable phase difference between the two arms, and recombining the two energy beams into a single beam. There is also provided an apparatus including a beam splitter in which an energy beam from an energy source is split into two arms, a variable delay unit in which a variable delay is imposed on one of the two arms, a constant delay unit imposing a constant delay on the other one of the two arms, and a recombiner in which the two arms are recombined to form a single output beam. A phase randomizer is interposed between the constant delay unit or the variable delay unit and the recombiner, to introduce a variable phase difference between the two arms.
