Ultrafast lasers in association to beam shaping have shown to be excellent candidates for transparent material processing [1]. Non-diffractive solutions such as Bessel beams allows for precise energy deposition since they are robust to undesired non-linear effects and as they do not distort along the propagation [2]. This offers important opportunities in laser-assisted cleaving, i.e. mechanical medium...
Control of the propagation properties of complex beams is desired for many applications. Here we present a novel method to generate propagation invariant shaped beams. Our method is based on a modified degenerate cavity (MDC) [1], [2], which has a huge number of degrees of freedom (300, 000 modes in our system), that can be coupled and controlled. Specifically, the MDC allows direct access to both...
Controlling the output beam of a multimode fiber (MMF) is quite a hot topic currently because it offers several attractive perspectives. Among the various technics used to shape the output beam of a multimode fiber, the adaptive approaches rely on a measurement (objective function) which feeds an algorithm for further command of a spatial modulator for optimization. This approach gives several advantages:...
