Powerful Laser Diode Matrixes for Active Vision Systems

This article is deal with the experimental
investigations of the laser diode matrixes (LDM) based on the
AlGaAs/GaAs heterostructures (lasing wavelength 790-880 nm) to
find optimal LDM parameters for active vision systems. In particular,
the dependence of LDM radiation pulse power on the pulse duration
and LDA active layer heating as well as the LDM radiation
divergence are discussed.
