<p>A power efficient continuous wave gas ion laser system and associated laser tube (14) are disclosed. An associated method is also disclosed. The system is configured for use with a fixed electrical input power and includes a power factor corrected power supply (12) which produces an output voltage and an output current using the fixed input electrical power such that the output voltage and the output current are substantially in phase. A gas ion laser tube (14) is configured for use in the system having a particular cavity length (C) which is established as a distance between a first mirror (22) and a second mirror (24) for operation using the output voltage and the output current. The tube (14) includes a bore arrangement (26) positioned between the first and second mirrors (22, 24) and defining a laser bore (28) including having an active gain length (L) in the range of approximately 25 percent to 35 percent of the cavity length (C). In one feature, the system may be configured to provide a light output power improvement of approximately thirty percent over prior art laser systems. In another feature, a laser tube (14) is configured for providing the aforementioned improved light output power in a conventional laser head configuration such that the laser tube (14) may directly replace laser tubes in prior art installations. In this manner, existing as well as new laser installations may benefit from the advantages of the present invention.</p> |
