The invention is directed to a compact optically side-pumped solid-state laser with an optimized overlap between the mode of the laser beam propagating in the laser material and the pump beam. Using a common pump volume the compact , solid-state laser can simultaneously emit laser beams at different wavelengths. The laser can be combined with nonlinear optical elements to provide a RGB three color laser architecture suitable for color projection display applications.

Why it's free to use
- Filed August 20, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 20, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 20, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
