JMDThèque's technology allows, thanks to its different optomechatronical devices, the use of several lasers in parallel for a variety of applications. This technology has the ability to control and superimpose different laser beams, to focus them at precise coordinates, and/or to scan samples surfaces.

The Optical Matricial Head (OMH) is a patented device allowing to generate collinear and collimated group of laser beams matrix (figure 1). This device is mainly constituted by the Optical Source Module (OSM) and the Optical Pyramid. The accurate positioning and alignment of the different laser heads (laser diode, fiber laser) are assured by the OSM (figure 2). The different beams reflect on the high quality mirrors of the Optical Pyramid, which assure their colinearity (figure 3).

Figure 6: Overview of the Digital MultiBeam Engine System combining the « OMH + Telescope + DBE » Sub-systems
In the figures above, the OMH and the Optical Pyramid are represented in their most basic configuration at 1 level allowing to work with 4 up to 7 lasers. BreizhTech has already developed and prototyped OMH and Optical Pyramid up to 5 levels able to work up to 128 lasers in parallel.
After the OMH, the colinear beams go through a Telescope with a Beam Reducer (figure 4), and are scanned (figures 5 and 6) thanks to the Digital Beam Engine (DBE). The DBE consists of two Optical Rotating Discs (ORD) allowing multibeams scanning : vertical deviation (DV) and horizontal deviation (DH). An electronic device controls the operating speed of the discs, and drive (shoot commands) independently each laser.
