We show for the first time to our knowledge, synchronization between two bulk semiconductor lasers onto an erratic train of pulses. They occurred erratically at different times, following a Poisson statistical law over a nanosecond scale. These pulses are due to excitability and are obtained using an optically injected bulk semiconductor laser. For the first time to our knowledge, two semiconductor lasers showing an erratic train of pulses are synchronized by cascading two optical injection schemes. The degree of correlation between the two signal outputs is analyzed following the detuning and the injected power. This correlation is related to the standard map obtained in the detuning-injected power chart for an optically injected laser, seeded by a non continuous wave. The synchronization on a single pulse is studied as well as on a regular temporal train of pulses.
