  • What do I need to do to become a Laser User?
    • Complete the initial online laser safety training (instructions here).
    • Complete Form LU-1 (Laser User Registration) and sign as the Laser User by typing your name in the indicated field.
    • Submit the form.
  • What material can I use as a laser barrier or laser curtain in my lab?

    The material to be used depends on the laser class and a variety of other factors. The LSO will determine the most appropriate barrier type as part of a laser hazard assessment. Generally, Class 4 lasers and some higher-powered Class 3B lasers will require the use of "laser rated" barrier material that has been tested to withstand up to a certain laser intensity and has been tested to be flame retardant.

  • How do I determine what laser eye protection to buy?

    The LSO calculates the optical density needed for protection against the wavelengths in use in your lab.  There are occasions where multiple optical densities are needed for a given wavelength.  For instance, an optical density of 4 might be needed for protection against an accidental exposure to a direct beam.  For the same wavelength, another pair of eyewear with optical density of only 2 would be sufficient for alignment purposes only.  Be sure to communicate with the LSO.

  • How often do I need to complete laser safety training?

    Laser Safety Training must be completed prior to your first use of a Class 3B or Class 4 laser. Refresher training is then required every 2 years.

  • What do I need to do to become a Laser Supervisor?

    You must be a full-time Georgia Tech faculty or staff member.
