Furthermore, this reduced learning was clearly related to the conditioned emotional response to the US images; individuals rated transfer images as positive if they had previously signalled the absence of a […]

The combining efficiency is above 80% and results in an output power of 6.7 W in a nearly diffraction limited beam. The rear side architecture is then used with a laser bar of 5 tapered emitters using an interferometric extended cavity, based on a diffractive optical element. [et al.], High power operation of coherently coupled […]
