Fundamentally there are several issues which are the life limiting constraints with any Gas Laser Device. A) The output power is proportional to the Input Current. The higher the Tube Current the Higher the rate of Gas Consumption. Therefore the Lifetime Is Inversly Proportional to the Tube current. B) There are other factors such as stability of the resonator which can result in artifical loss of power (result is, turn up the current to get the power you need) valla lower life! Internal Contamination again artifically decreasing the effeciency of the laser (again turn up the power-- turn down the life)! C) Items critical to extending the life of the laser. 1) Operate the laser at optimal alignment (Adequate power at minimum current. 2) Utilize Standby (when not scanning reduce the current to 3-4amps (at 3-4 amps the laser should last 4-5Khrs). 3) Select a Laser that gives you the best dynamic range of operation at the lowest Tube current. Good Luck LaseRay Contact me if you need further information on Noise, Power, Lifetime Specific wavelength information etc.
