RESUMO
In this work the implementation of a measurement system of short optical pulses generated by semiconductor lasers is presented. This indirect method estimates the pulse duration using the internally generated second harmonic radiation from these lasers. The main theoretical and experimental considerations related with the second harmonic emission are also presented. Although the precise pulse duration requires aditional measurements it is possible to estimate the duration of optical pulses generated by gain-switching and mode-loching regimes with good time-resolution.
