Hollow-cathode transverse discharge He−Ne and He−Cd+ lasers


An all-metal hollow-cathode laser tube consisting of a perforated cylindrical cathode surrounded by a coaxial cylindrical anode has been operated as a He−Ne laser at 0.6328, 1.15 and 3.39 μm, and as a He−Cd laser at red, green and blue visible wavelengths, using both de and pulsed-plus-dc excitation. Laser oscillation in He−Zn, Ne−Cd, Xe−Cd and Ar−Cd mixtures has also been obtained. The hollow-cathode discharge consists primarily of an intense cathode glow inside the cathode cylinder, giving a quiet, stable, low-voltage, positive-resistance discharge. Results for the He−Ne and He−Cd laser output versus partial and total pressures and discharge currents are presented. The unoptimized laser performance for the He−Ne case approaches but does not yet equal the conventional positive-column case, while the He−Cd performance for the charge-transfer-pumped green 5378Å line appears particularly promising.
