Wavelength-Stabilization of Extended-Cavity Tapered Lasers with Volume Bragg Gratings

Abstract : The wavelength stabilization of high-brightness extended-cavity lasers at 810-nm by use of volume Bragg gratings is described. Narrow linewidth (< 20 pm), high power (2.5 W) and good beam quality (M2 < 4) operation has been obtained in a robust and simple design. The impact of the beam focusing into the Bragg grating on the external-cavity performance has been theoretically and experimentally investigated. Finally, second-harmonic generation of the infrared beam has been obtained in a ppKTP crystal, demonstrating a non-linear conversion efficiency of 0.8%/W and up to 8 mW at 405 nm.
