Open the CIPO recordAbstract From the Canadian patent
Ring and linear cavity, fiber optic laser systems are disclosed employing non-, invasive fiber optic amplification technology. A channel overlay waveguide (60) is employed for amplification of optical energy evanescently coupled to the overlay waveguide (60) from the fiber optic (30). One of two amplification methods can be employed. The first involves inducing stimulated emission with the overlay waveguide (60) and the second uses a second order non-linear , frequency conversion to down-convert a high-power short-wavelength pump , signal into the waveguide (60) to amplify the optical energy coupled thereto. Amplification of optical energy in the channel overlay waveguide (60) can be …

Why it's free to use
- Filed February 19, 1999 and granted November 11, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 19, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
