Abstract
A device for analyzing the distribution of energy within a power laser beam includes a thermoelectric receiver (1) directly exposed to the laser beam (2) and delivering electrical signals to an intermediate demultiplexer and amplifier device. The device operates in continuous mode and in impulse mode, the thermoelectric receiver being constituted by a sealed body (5) whose surface turned toward the source of the laser beam is metallic and constitutes, in cooperation with metallic wires (7), the support of the thermocouples. The wires (7) pass in sealed manner through the surface (8) of the body (5) opposite the surface turned toward the source of the laser beam (2), and the body (5) is provided moreover with two openings (9) for circulation of a cooling fluid. The receiver (1) is integrated into the rear surface of a mirror (18) of the laser cavity, this mirror (18) forming the forward surface of the receiver (1), such that is is possible to analyze continuously the distribution of intensity within a laser beam during a fired pulse or continuously, by the use of a pattern of thermocouples connected to a computer, the receiver (1) being directly and continuously exposed to the beam and permitting visualization in real time of the distribution in the beam.
