Abstract
The present invention relates to a device (IO) for controlling the axial position of a laser focal point produced by a microscope objective, comprising:—a laser source for emitting a laser beam,—a deformable mirror for focusing or defocusing the laser beam axially,—a microscope objective for focusing the laser beam coming from the deformable mirror on a laser focal point, characterized in that it further comprises a system for passing the laser beam emitted by the laser source several times through the deformable mirror.

Device for controlling the axial position of a laser focal point produced by a microscope objective, comprising:
- a laser source for emitting a laser beam,
- a deformable mirror for focusing or defocusing the laser beam axially,
- a microscope objective for focusing the laser beam coming from the deformable mirror on a laser focal point,
- a system for guiding the laser beam emitted by the laser source several times on the deformable mirror, the system for guiding the laser beam several times on the deformable mirror comprising at least one set of two mirrors for guiding the laser beam between two successive reflections of the laser beam on the deformable mirror, and an optical relay system (f1, f2;
- f3, f4;
- f5, f6) for conjugating the deformable mirror plane with the next deformable mirror plane between said two consecutive reflections.
