Vv. Bezotosnyi et al., CHARACTERISTICS OF THE EMISSION OF 805-81 0-NM RADIATION BY LINEAR INJECTION-LASER ARRAYS USED TO PUMP SOLID-STATE LASERS, Kvantovaa elektronika, 22(2), 1995, pp. 101-104
Integrated linear injection-laser arrays were made from AlGaAs/GaAs he
terostructures grown by MOCVD epitaxy. The total width of the emitting
surface was 1 cm and the arrays were intended for the pumping of soli
d-state lasers. The watt-ampere characteristics, the overall efficienc
y, the emission spectra, and the shape of the light pulses emitted by
the arrays were investigated in the 0.1 - 1 ms range of the pump pulse
durations, best for the optical pumping of solid-state lasers. The ma
ximum pulse power of 70 W, obtained for a current of 80 A, was limited
by the source used to pump the injection lasers.
