An investigation was made of inhomogeneously pumped injection lasers in the form of Al/sub x/Ga/sub 1-x/As--GaAs double heterostructures. Bistable operation of such lasers was demonstrated and the switching time between the two states was less than 2 x 10/sup -10/ sec. A study was made of regular pulsations of the output radiation resulting from inhomogeneous pumping. The pulsation frequency was tunable up to 2 GHz and the duration of each pulsation (spike) was less than 2.5 x 10/sup -1/ sec. It was found that the pulsation frequency obeyed fproportional(I-I/sub th/)/sup 1/2/, where I and I/sub th/ are the current through the heterodiode and the threshold value of this current, respectively.
