Journal ArticleDOI
Blue light generated by frequency doubling of laser diode light in a lithium niobate channel waveguide
TL;DR: In this article, LiNbO/sub 3/ channel waveguide was used to generate blue light by frequency doubling radiation from a laser diode in a guided to guided wave interaction, utilizing first-order quasi-phase matching in a periodically domain inverted structure.
Journal ArticleDOI
Transmission measurements in KTP and isomorphic compounds
TL;DR: Variations in spectral transmission on the short- and long-wa wavelength edges, as well as visible-wavelength transmission and OH(-) absorption properties, are presented and discussed.
Journal ArticleDOI
Improved photodarkening resistivity in ytterbium-doped fiber lasers by cerium codoping
TL;DR: It is suggested that the coexistence of the redox couple Ce(3+)/Ce(4+) in the glass provides means for trapping both hole- and electron-related color centers that are responsible for the induced optical losses in Yb-doped fiber lasers.
Journal ArticleDOI
Development and characterization of Yb-Er laser glass for high average power laser diode pumping

TL;DR: A new strong erbium laser glass (SELG) based on a boro-alumo-phosphate composition is reported in this article, where the synthesis and chemical properties together with spectroscopic and thermo-mechanical properties are discussed.
Journal ArticleDOI
Fabrication of periodically domain-inverted channel waveguides in lithium niobate for second harmonic generation
TL;DR: In this paper, a method to produce periodically domain-inverted channel waveguides in LiNbO/sub 3/ was proposed, where arbitrary wavelengths can be frequency doubled by choosing the appropriate period.
