We report the use of gain guiding in a Ti:Al(2)O(3) rod to produce 150-mJ tunable pulses from a flat-flat resonator with an excellent efficiency. The output beam is Gaussian and 1.3 times diffraction limited.

One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificial potentials, giving insight into phenomena of quantum fluids in hard-to-reach settings. A prominent example is the matter-wave scatterer lattice, where high energy matter waves undergo transmission and reflection through narrow width barriers leading to stringent phase matching conditions with lattice band formation. In contrast to evanescently coupled lattice sites, the realisation of a scatterer lattice for macroscopic matter-wave fluids has remained elusive.
