An apparatus, is described for examining transient processes and for recording watt-ampere and quasi-resonant emission characteristics from injection lasers working under pulse conditions and with pulse-code modulation. The risetime of pumping current pulse does not exceed 1 nsec, while the interval between two pulses in a code sequence is set in the range 0-20 nsec, which enables one to examine the modulation characteristics at frequencies close to the limiting one.
