ABSTRACT:
The invention disclosed is a dual wavelength output laser for use in laser rangefinders. Two different laser active media, e.g. CO.sub.2 and DF, are operated in separate laser cavities arranged in tandem in the same optical resonant cavity, resulting in a co-linear dual wavelength laser output.
