Abstract :
Summary form only given. There is considerable interest in compact lasers that operate in the blue spectral region. A blue laser source combining a diode laser with a waveguided nonlinear crystal represents such a compact source which is also stable, self-contained and has a low overall cost. By using a picosecond-pulse diode laser with a periodically-poled KTP waveguide crystal a coherent blue source at an average power of 3.9 mW has been demonstrated. To achieve efficient second harmonic generation (SHG) from the diode laser we designed a two-section waveguide crystal with a periodic grating structure and a Bragg grating, where this grating was fabricated to facilitate non-resonant injection seeding of the diode laser.
