“…It has been shown that these mirrors can be engineered to withstand radiation power densities up to 3 kW/cm 2 for continuous sources and roughly 1010 W/cm 2 for pulsed sources [11]. External to the laser cavity, these deformable mirrors have also shown wavefront correction and distribution compensation with both wide and small aperture mirrors [12][13][14][15]. Extending this to spatial-profile control, these mirrors have been demonstrated to produce elliptical and rectangular super-Gaussian and annular beam-shapes [16][17][18] and Bessel modes via a magnetic fluid-based liquid deformable mirror [19].…”

The number of mirror segments, mirror geometry and orientation are essential parameters when assessing the beam-shaping capabilities of deformable mirrors. Here, we use a Liquid Crystal on Silicon Spatial Light Modulator (LCoS-SLM) to mimic the mechanical design of a deformable mirror and quantitatively analyse the effect of the number of mirror segments and their geometrical structure on resulting structured modes. Our approach can be used as a test bed prior to designing a deformable mirror for high power beam shaping.

“…Among all possible technologies for the realization of DMs, which includes electrostatic membrane [10] , piezoelectric bimorph [11] or continuous facesheet with piezostack actuators [12] , electromagnetic [13] and mechanical actuators [14] , the most suitable ones are the piezoelectric (PZT) and mechanical actuators. The reason is that bimorph and piezostack DMs and the mechanical actuators can be realized mounting a high reflectivity high damage threshold dielectric coating.…”

We present the workflow of the design, realization and testing of deformable mirrors suitable for high power diode pumped solid-state lasers. It starts with the study of the aberration to be corrected, and then it continues with the design of the actuators position and characteristic. In this paper, we present and compare three deformable mirrors realized for multi-J level laser facilities. We show that with the same design concept it is possible to realize deformable mirrors for other types of lasers. As an example, we report the realization of a deformable mirror for femtosecond lasers and for a CW CO 2 laser.
