Abstract: A laser source for industrial operations including a first laser outlet and a second laser outlet. The laser source is switchable to selectively provide at the first laser outlet a high beam quality and relative low power or at the second laser outlet with a higher power and lower beam quality to better accommodate the particular process. In one example, a selector addressing unit includes movable mirrors to selectively direct the generated laser beams to either the first laser outlet or the second laser outlet. In another example the laser source is used in an industrial plant to provide laser beams to a plurality of processing cells. The laser source operable to selectively provide a laser beam having desired or optimum qualities for the particular processing cell.

Abstract: An apparatus comprises a multi-clad fiber that includes a light-guiding core surrounded by at least a cladding layer, and an input interface including a first set of input channels in the core configured to receive a first optical fiber, and a second set of input channels in the cladding layer configured to receive a second optical fiber. The apparatus further includes an optical switch module having an input port, a first and a second output port, a first optical path between the input port and the first input channel, and a second optical path between the input port and a second input channel in the second set of input channels. The optical switch module is controllable to switch between the first and the second optical paths. The apparatus also includes a set of laser modules.

Abstract: A method for making a laser diode with a distributed grating reflector (RT) in a planar section of a semiconductor laser with stabilized wavelength includes providing a diode formed by a substrate (S), a first cladding layer (CL1) arranged on the substrate (S), an active layer (A) arranged on the first cladding layer (CL1) and adapted to emit a radiation, and a second cladding layer (CL2) arranged on the active layer (A), said cladding layers (CL1, CL2) being adapted to form a heterojunction to allow for efficient injection of current into the active layer (A) and optical confinement, and a contact layer. The manufacturing method provides for creating, on a first portion (ZA) of the device, a waveguide (GO) for confinement of the optical radiation and, on the remaining portion (ZP) of the device, two different gratings for light reflection and confinement.

Abstract: A laser-diode device includes a substrate; at least one first cladding layer placed on the substrate; an active layer placed on the first cladding layer and arranged to emit a radiation; at least one second cladding layer placed on the active layer, said cladding layers being adapted to form a heterojunction; a first terminal facet and a second terminal facet placed transversally relative to the cladding layers and to the active layer; a periodic structure, placed in proximity to the second terminal facet and within the second cladding layer, and belonging to an optical cavity, wherein the first terminal facet represents the output mirror from which the radiation generated by the active layer exits, and the second terminal facet, integrated by the periodic structure, represents a second mirror having high reflectivity, so that the radiation produced by the active layer exits almost totally through the first mirror.

Abstract: A laser source for use in providing a laser beam for industrial operations in an industrial plant. The laser source selectively providing a first laser beam at a first outlet having relatively high power and lower beam quality and a second laser beam at a second outlet having relatively lower power and higher beam quality. The laser source including an optical path selector device for selectively transmitting a first laser beam along a first or second optical line toward respective first and second outlets. The second optical path having an optical amplification unit for changing the first laser to the second laser. An industrial plant including at least a first laser source selectively controls the first laser source to provide the first and the second lasers to predetermined laser processing stations. A second laser source may be used and controlled to provide a first or second laser to an alternate laser processing station on a failure of another laser source.
