Using the 612 nm He-Ne laser tube made in the National Institute of Metrology (NIM) and the wide-band mirriors with the reflectivity of 99.95 %, simultaneous emission of 6 visible laser wavelengths (611.8, 629.3,632.8, 635.1, 640.1 and 650 nm) has been observed. Various physical parameters of these lines have been measured and the laser frequency has been stabilized with simple devices. The frequency stability is better than 10-10 for all 6 lines. This can be improved up to 10-12 using modelocking technique. The 650 nm line is proved being a CW He-Ne Raman emission.
