“…The design of this laser head and comparison of the predictions of the FEM with analytical results have been reported in detail elsewhere. 8,15 We have constructed a 2D and a 3D FEM. The 2D model can be used to calculate the temperature and stress distributions at high resolution for a cross section perpendicular to the z axis.…”

“…Pumping and cooling can be parallel and uniaxial, through the large lateral slab faces, in principle drastically reducing the effect of thermal distortions. From the 1990s several diode-pumped devices have been constructed using this scheme [2]- [4]. Recently high energy multi Joule versions for Inertial Fusion Applications, like the HALNA Laser [5], or high power multi Kilowatt ones, like the ThinZag Laser [6], have been developed based on a face-pumped zig-zag slab geometry.…”

A new thin-slab ceramic Nd:YAG laser is presented based on a non-conventional zig-zag configuration. The slab is shaped in such a way that the beam propagates internally bouncing on the thin lateral faces (Edge zig-zag). Preliminary experiments have demonstrated a power extraction of 170 W (CW) at an optical conversion efficiency of 36%. Measurements have also been performed to assess the propagation properties, at least in the thinner transverse direction, of the beam extracted with a simple stable resonator. This laser format appears as a good competitor of the more traditional face-pumped or edge-pumped zig-zag slab laser schemes.

“…Since the slave laser should be compact to improve servo reliability, the former requirement often leads to a modulation frequency 50-150 MHz, and the technique thus requires an electro-optic modulator (EOM). For injection-locked chain architectures, in which a medium power injection-locked laser is used to injection-lock a high power slave laser [9], [13], [14], the EOM must be able to transmit relatively large CW powers without introducing intensity or polarization modulation. Alternatively, the phase-modulation side-bands could be imposed using a Mach-Zehnder interferometer that has a low-power EOM in one of its arms and uses a control system to minimize the power transmitted into one of the outputs of the recombination beamsplitter.…”
