  "abstract": "A laser connection module including: multiple superposed electrodes connected in alternating order with opposite electricity supply poles; at least one laser diode mounted between the opposite surfaces of consecutive electrodes, making contact with them; an external structure delimiting an open space located along a light-emitting area of the laser diodes and suitable for containing the set of superposed electrodes and laser diodes; at least one tightener mounted on a first end of the external structure and which presses the set of electrodes and laser diodes against a second opposite end of the structure, establishing the fixation and mutual contact thereof; and an intermediate protective plate disposed between the at least one tightener and the end electrode closest to the at least one tightener.",
  "claims": [
    "1. A laser connection module comprising: a plurality of superimposed electrodes connected alternately with opposing electrical power supply poles; at least one laser diode mounted between and in contact with facing surfaces of consecutive electrodes of said plurality of superimposed electrodes; a clamping structure that connects said plurality of superimposed electrodes with said at least one laser diode; an external structure having a space with a light emissions zone of said at least one laser diode, said external structure housing said clamping structure of said plurality of superimposed electrodes and said at least one laser diode, said clamping structure comprising studs mounted on threaded holes at one end of said external structure, said clamping structure urging said plurality of superimposed electrodes and said at least one laser diode against an opposite end of said external structure so as to establish contact of said at least one laser diode with a facing surface of the consecutive electrodes, said external structure comprising: an upper part forming the one end of said external structure; a lower part forming the opposite end of said external structure; and a fastener that fastens said upper part and said lower part in parallel relation, said upper part and said lower part being vertically separated by a suitable distance for an unconstricted housing of said plurality of superimposed electrodes and said at least one laser diode between said upper part and said lower part; and an intermediate protection plate positioned between the clamping structure and an end electrode of said plurality of superimposed electrodes closest to said clamping structure.",
    "2. The laser connection module of claim 1, wherein said upper part is fastened to said lower part with fastening screws.",
    "3. The laser connection module of claim 2, wherein said fastener is a plurality of tubular spacers positioned between said upper part and said lower part, wherein the plurality of tubular spacers are mounted on the fastening screws.",
    "4. The laser connection module of claim 3, further comprising: a plurality of pins housed in aligned vertical holes in the consecutive electrodes and in at least one of said upper part and said lower part of said external structure.",
    "5. The laser connection module of claim 3, wherein said at least one laser diode is arranged between front ends of said plurality of superimposed electrodes, the laser connection module further comprising: electrically insulating spacers located between consecutive rear ends of said plurality of superimposed electrodes, said electrically insulating spacers having a thickness corresponding to a thickness of said at least one laser diode.",
    "6. The laser connection module of claim 5, said clamping structure further comprising: a plurality of front studs that urge a front end of said plurality of superimposed electrodes against said at least one laser diode; and a plurality of rear studs that urge a rear end of said plurality of superimposed electrodes against said electrically insulating spacers.",
    "7. The laser connection module of claim 1, wherein said fastener comprises: a plurality of guide columns arranged between said upper part and said lower part and fastened thereto by screws to said upper part and said lower part.",
    "8. The laser connection module of claim 7, wherein each of said plurality of superimposed electrodes has a recess complementary to a portion of a respective guide column of said plurality of guide columns so as to assemble said plurality of superimposed electrodes as respective sliding elements between adjacent guide columns of said plurality of guide columns, said plurality of guide columns separating said upper part of said lower part of said external structure and to vertically align said plurality of superimposed electrodes.",
    "9. The laser connection module of claim 1, wherein the front studs are centered relative to the assembly of said plurality of superimposed electrodes and said at least one laser diode."
