A chemical process yielding laser amplification and oscillation in the visible and ultraviolet spectral ranges comprising the steps of chemically reacting metal polymers with halogen atoms to form a lasing medium (12) comprised of electronically excited metal dimer molecules which produces laser amplification and by providing a, mirror configuration (90 91) which makes use of the, inverted population through multiple reflection allows, for laser oscillation by the repeated passage of light through the inverted gain medium (12).

Why it's free to use
- Filed January 3, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 3, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 3, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
