New Laser Replacement Tube

Replacement Laser Tubes

New Tube Replacement

When refurbishing an argon laser head with a new tube, the primary component of the laser is entirely replaced. Matching the original specifications, National Laser replacement tubes are fit, form, and function compatible with the original design of the laser. National Laser's replacement tube designs result in improved performance and increased lifetimes over competitor's products. In addition to replacing the entire laser tube with new material, National Laser inspects, and if necessary, replaces damaged components in the laser head in order to offer a new laser warranty..

Re-Gassing or Re-Manufacturing Lasers

In re-gassing or re-manufacturing ion lasers, quality and performance concerns should be considered when choosing new versus old laser products.

  1. New Charge of Argon Gas
    • Simply adding gas to an argon tube will not restore the tube to original performance.
  2. Not Replacing the Optic
    • The coating on the inside of the output or reflective optic deteriorates from high energy levels. In addition, deposits may form on the optic. This buildup and/or breakdown decreases beam quality and tube lifetimes.
  3. Not Replacing the Cathode
    • Once the cathode fails due to deterioration, the tube will not light and will need replacement.
  4. Contaminated Ceramic Bores
    • Material buildup and bore degradation occurs during the normal life of an ion laser. Once a tube reaches the end of life and is re-gassed, the buildup and degradation continues to decrease performance and shortens lifetime.
  5. Ceramic Bore Reprocessed
    • Due to the nature of ion lasers, both buildup and breakdown occurs within the laser bore. For this reason, it is difficult to achieve consistency in performance and lifetimes. Material deposits form in the inside capillary of the ceramic bore, causing material inconsistencies, which affect output power and lifetimes. In the reaming or cleaning process, the enlarged capillary creates inconsistencies with the original design. This results in output power losses and changes in mode structure.
