Measurements of the noise fluctuations in the light intensity emitted by stripe-geometry junction lasers are used to relate the threshold for amplitude-stabilized oscillation to the behavior of the first and second derivatives of the diode's electrical characteristics. The amplitude stabilization is observed to begin at a current above the point where the second-derivative signal attains its maximum value but below the current at which the junction voltage is fully saturated. Consequently, the electrical derivatives do not, in general, sense the exact threshold current but only provides bounds on its value. (AIP)
