Abstract
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 $\text{CO}_{2}$ laser.
Highlights
Deformable mirrors (DMs) have been used since the 70s in astronomy and high power laser propagation for the correction of the disturbance induced by the atmosphere
We present here three different DMs developed for wavefront correction in multi-slab laser amplifiers
They have been tested in terms of achievable magnitude of single Legendre terms, as shown in Figure 5 and compared with the calculated HiLASE aberration determined with the Mirosoftware
Summary
Deformable mirrors (DMs) have been used since the 70s in astronomy and high power laser propagation for the correction of the disturbance induced by the atmosphere. One of the latest most important applications is in the field of the correction of aberrations in high power lasers. The wavefront correction due to thermal aberration has become one of the most crucial aspects of the design of high-energy and highaverage-power lasers. For this applications, DMs have to be realized with a very high damage threshold to withstand the laser peak energy and a high reflectivity to avoid thermally induced aberrations on the DM itself
