Abstract : The patent discloses a laser cavity configuration which enables a single laser medium (gas, liquid or solid) to give an output at least one wavelength from one end of the laser and another output at different wavelengths from the other end of the laser. Disclosed are several well known laser media which are capable of simultaneous laser oscillation at two or more wavelengths. Mirrors which are highly reflective at one of such wavelengths and highly transmissive at another of such wavelengths can be prudently selected to resonate the emission from an active medium. If each of the two mirrors thus required are optimized for reflectivity at one of the wavelengths and transmissivity at the other, the desired effect will result.
