Green electron‐beam pumped laser arrays based on II–VI nanostructures

Room temperature electron‐beam pumped (U = 15–26 keV) green lasers and laser arrays based on multiple quantum well II–VI structures with an extended up to 2 µm waveguide have been studied. The maximum achieved output pulse power is as high as 31 and 630 W per facet from a single 0.24‐mm‐wide laser element at the cavity length of 0.4 mm and a laser array consisting of 26 elements, respectively.
