| Popis: | 98 In recent years, pico-second and femto-second optical pulses have been used in biophotonic applications such as nonlinear multiphoton bioimaging and coherent anti-Stokes Raman scattering (CARS). As ultrashort optical pulse sources, mode locked solid-state lasers are generally used for multiphoton bioimaging. However, these lasers are large, costly, and not maintenance free. Therefore, for real world biophotonic applications it is necessary to develop a turnkey ultrashort optical pulse source that is simple, compact, and low cost. The research investigated the pulsing characteristics of Fabry-Perot type semiconductor lasers subject to optical feedback. Stable pulse trains with a pulse width 78 ps and repetition rate 225.88 MHz are generated by careful adjustment of DC bias, and cavity length. This discovery constitutes an important contribution to our understanding of applications of semiconductors. |
