H. Yang et al., 10W NEAR-DIFFRACTION-LIMITED PEAK PULSED-POWER FROM AL-FREE, 0.98-MU-M-EMITTING PHASE-LOCKED ANTIGUIDED ARRAYS, Electronics Letters, 33(2), 1997, pp. 136-137
10 W peak-pulsed power emitted in a beam pattern 2xdiffraction limit (
DL) is obtained from a 40-element, 200 mu m-aperture Al-free phase-loc
ked antiguided array (lambda = 0.98 mu m). 60% of the power resides in
the central lobe, and the external differential quantum efficiency is
54% for 1 mm-long optimised facet-coated devices.
