Open the CIPO recordAbstract From the Canadian patent
The invention pertains to laser technology fibre optics and integrated optics , and has industrial applicability in the field of fibre-optical and waveguide elements made from germano-silicate glass, in particular in fibre-optical Bragg and longperiod gratings, dispersion compensators integrated optical waveguides and so , forth. The invention solves the problem of simplifying Raman fibre-optical lasers operating at wavelengths of 1.24 µm and 1.48 µm and enhancing the efficiency of the radiation conversion associated with Raman scattering. The 1.24 µm laser comprises a pumping source (1), a fibre-optical waveguide (2) containing 1-30 Mol % P2O5; sections of the fibre-optical waveguide …

Why it's free to use
- Filed July 5, 1996 and granted February 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 5, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 5, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
