“…The pulsation frequency increases above threshold in a linear fashion until selfpulsation ceases. For most of the current range the device operates in a large signal modulation regime 12 where the recovery time of the absorber (carrier lifetime in the absorber quantum well) is much shorter than that in the gain region. In this regime the pulsation frequency is directly related to the rate at which charge carriers can be replenished in the gain quantum wells, and a linear relationship results.…”

We report on the development of a stroboscopic excitation technique using a self-pulsing laser, and show that it is a feasible method for obtaining fluorescence lifetime information from a biochip format. The self-pulsing lasers described here are versatile devices which have been used for one photon excitation measurements to determine the lifetime of cyanine 5 in water and ethanol. The same devices have been used to develop a technique whereby the emphasis for time-resolution of a lifetime measurement can be transferred to the excitation source from the detector and processing electronics by virtue of the multiple-pulse, variable frequency nature of the laser output.

“…Self-pulsating semiconductor lasers can generate pulsating oscillations without any external modulations according to their unique device structures. [3][4][5][6] Indeed, self-pulsating lasers are used for digital versatile disk (DVD) systems to reduce optical noises induced by optical feedback from disk surfaces. Although they are aimed to reduce optical feedback noises, noises are sometimes much enhanced under certain conditions of feedback configurations.…”

Self-pulsating semiconductor lasers are deviced to reduce optical feedback noises as light sources in optical data storage systems. However, they themselves include instabilities in their solitary oscillations without any optical feedback and they also show unstable behaviors induced by optical feedback. We experimentally investigate instabilities and dynamics of self-pulsating semiconductor lasers without and with optical feedback from a distant reflector on the order of several tens of centimeters to one meter.
