Abstract

Blue light with an average power of as much as 7.5  mW in picosecond pulses has been generated at 486, 488, and 491  nm from a frequency-doubled, nonresonant injection seeded, gain-switched InGaAs/GaAs diode laser by use of a periodically poled KTP waveguide crystal that incorporates a Bragg grating section.
