Self-pulsing Ti:Er:LiNbO3 waveguide laser

摘要

The self-pulsing laser reported here was fabricated in a 92 mm long Er-diffusion doped Z-cut LN substrate with a surface concentration of about 1.24 x 1020 cm-3 and a diffusion depth of 8.4 mum. Ti stripes of 7 mum width were indiffused to define single mode waveguides for the 1550 nm wavelength range. The laser cavity was formed by two dielectric multilayer mirrors, one of them vacuum-deposited on the input/output face of the Ti:Er:LN waveguide.
