Making A Difference

Tetra has over 200 years of combined technical & management experience in Pulsed Power R&D, design, fabrication, and commercialization.  Our facility and equipment are located in Albuquerque, NM.

Our History

Since 1977, Tetra has been working to develop advanced technologies for government and commercial projects.

  • 1977

    Tetra was founded to develop advanced pulsed electric laser technologies.

  • ELF Codes

    Tetra developed the "ELF" codes for design of Gas Discharge Laser Electrodes.

  • 1985 - 1992

    Tetra developed numerous Pulsed Power Systems for SDI ("Star Wars")

  • PBFA-II

    Tetra used the "ELF" Codes for modeling of laser-triggered gas switches on Sandia's PBFA-II

  • Late 1990's

    Tetra shifts focus to commercial markets.

  • 2002

    Tetra focuses efforts on rock drilling and development of the RePED technology.

  • 2018 to Present

    Tetra works toward the commercialization of RePED, HV switch development, and mining applications.
