Single-mode gain-switched operation of a self-seeded 690-nm InGaP/AlGaInP Fabry-Perot laser

Summary form only given. We have successfully demonstrated the single-mode operation of a gain-switched 690-nm InGaP/AlGaInP Fabry-Perot laser by the self-seeding technique. We believe this scheme will lead to the efficient generation of single-mode pulses and is attractive for applications in short-wavelength nonlinear optics.
