We investigate the potential of large optical cavity (LOC)-laser structures
for AlGaInP high-power lasers, For that we study large series of broad are
a lasers with varying waveguide widths to obtain statistically relevant dat
a. We study in detail I-th, alpha (i), eta (i), and P-max, and analyze abov
e-threshold behavior including temperature stability and leakage current. W
e got as expected for LOC structures minimal alpha (i) less than or equal t
o 1 cm(-1) resulting in eta (d) = 1.1 W/A for 64 X 2000 mum(2) uncoated dev
ices. We obtain total output powers greater than or equal to3.2 W (qCW) and
greater than or equal to1.5 W (CW) at 20 degreesC.
