RLSS training provides technical knowledge required to perform laser range hazard evaluations and calculations for laser range certification. An RLSS must successfully complete an ALA/LNTL-approved RLSS course. TLSO certification is a pre-requisite for the RLSS course. An RLSS is qualified to: Conduct laser radiation hazard surveys and evaluations for commanding officer certification. Perform the calculations and measurements required to certify a laser range. Train ALSOs and RLSSs using the ALA-approved course curriculum. (Qualification of instructors requires ALA/LNTL approval.) Conduct technical aspects of laser range incident investigations. Perform the same tasks as a TLSO.
