Design of deformable mirrors for high power lasers

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 e… Show more

“…The main advantage of this approach is that it does not require any sensors for measuring f sys . This is important for making the FC system compact, since adaptive optical systems that operate in closed-loop often require the use of beam splitters and optical sensors such as photodetectors or wavefront sensors [18]. However, the drawback of this method is that it is strongly dependent on the accuracy of the model, which may be difficult to guarantee due to the number of parameters involved.…”

“…Bimorph DMs use the transverse piezoelectric effect to control the curvature of the DM [19]. These DMs offer high reliability, large stroke, and high accuracy [23], but require high voltages and are limited to actuator counts of ∼200–300 [19]. Voice coil actuator DMs use the Lorentz force to control the shape of a thin floating optical shell [19].…”

“…For example, AO has been successfully used to increase the yield of non-linear phenomena exploiting iterative optimization algorithms 21 23 or to correct for wavefront aberrations induced by uneven thermal dissipation 24 26 . In the latter cases, the aberrations were corrected using a wavefront sensor and a closed loop control operating at 10 Hz.…”
