A multi-wavelength He-Ne laser tuned by a dispersion prism has been developed. Laser lines of eight different wavelengths in visible region have been obtained with 30 mW output power at 6328 A and 10 mW at 6118 A. Some problems on the design of this laser are discussed and its performances are described.
