HIGH PULSE POWER INJECTION LASER.

Abstract

Peak power outputs as high as 70 watts have been obtained from one facet of single GaAs injection laser diodes operated by pulse excitation at room temperature. These power outputs have been attained at four times the threshold current. Studies concerned with elucidating the nature of the degradation process have shown that two distinctly different mechanisms exist. The first is of a catastrophic nature and results from the mechanical destruction of the laser cavity. The second process consists in a gradual degradation in power output which may occur under operation at flux levels below those required for catastrophic damage, but without any detectable mechnical facet damage.
