Abstract
Properly dimensioned aluminum cold cathodes promise single mode 6328 Å He‐Ne gas laser lifetimes exceeding 3000 h with total gas volumes of only 50 cm3. These cathodes are simple, rugged, and require only about 0.5 W for an emission current of 5 mA dc. Beryllium cold cathodes may be even better but more time is needed for their evaluation.Keywords
