Paper Abstract

In this paper, the dynamic emission spectra of high- frequency pulsed laser diodes have been studied in order to investigate the spectral stability of each laser pulse and to examine the influence of the HF-pulsed laser diode's mode hopping and frequency jitter on the interferential fringe system in LDA applications. It has been shown that, by choosing appropriate operating points, a HF-pulsed laser diode can be operated to have optical characteristics such as mono-mode emission, a stable wavelength from pulse to pulse and high optical output peak power. The selection of optimal operating points for LDA applications may be not required if semiconductor lasers with periodically structured laser resonators of for example the distributed- feedback type or the distributed-Bragg-reflector are used.
