Abstract: Apart from a frame (10) that may be formed of parts mutually free to move in translation, the mirror support comprises a lever (29) suspended from a console (28) by springs (30) and position adjustment screws (33,34) to apply the required orientation with excellent precision; the mirror is attached to this lever. It may be fitted on a rotating tray to put it into the required angular position. This invention is applicable to oscillating laser cavity mirrors because the position of the mirror may be adjusted with extreme accuracy and fixed reliably.

Abstract: A laser bar assembly module having a metal base plate (20) to support a diode or a laser diodes strip (22), this base plate being provided with a groove or area (21) holding the diode or diodes strip in position, a support (24) on which the metal base plate is installed, this support being provided with a flat laser bar bearing surface (26), this flat surface projecting along a direction perpendicular to it beyond the groove or area (21) holding the diode or diodes strip in position.
