Open the CIPO recordAbstract From the Canadian patent
A scalable high power laser system includes a plurality of parallel connected modular power amplifier arms, coupled to a common master oscillator to provide a high, average power laser system with a scalable output power level particularly , suitable for laser, weapon systems with varying power level output applications. Adaptive optics devices are, provided in order to provide pre-compensation of phase front distortions due to the modular, amplifier arms as well as encode the wave front of the laser beam with a phase conjugate of, atmospheric aberrations.

Why it's free to use
- Filed April 1, 1999 and granted February 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 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.
