Abstract

Summary form only given. We report on the fabrication of second order nonlinear gratings up to 7.5 cm long for quasi phase matched (QPM) SHG of 1.5 /spl mu/m and their use for ultrashort pulsed frequency conversion. It is shown that periodically poled glass fibres (PPGF) are very promising for QPM-SHG and parametric processes involving highpower laser sources.
