What is it?
PHaSR, or Personnel Halting and Stimulation Response, is a rifle sized counter personnel non-lethal laser weapon system. PHaSR achieves the desired degree of protection through the synergistic application of two non-lethal laser wavelengths during the course of protection activities that will deter, prevent, or mitigate an adversary’s effectiveness. The laser light from PHaSR temporarily impairs aggressors by “dazzling” them with one wavelength. The second wavelength causes a repel effect that discourages advancing aggressors.

PHaSR is the first-of-a-kind self-contained non-lethal system that can be operated by a single user. This is accomplished by incorporating an innovative power source that makes the system completely self-contained. PHaSR uses two low-power diode-pumped lasers; one visible wavelength and one mid-infrared wavelength.

Organizations Involved
Funding for PHaSR is being provided by the Joint Non-Lethal Weapons Directorate (JNLWD) and the National Institute of Justice (NIJ). JNLWD is looking at PHaSR for military applications and NIJ is looking at PHaSR for civil law enforcement applications. The bioeffects of the two laser wavelengths are currently being studied by the Air Force Research Laboratory Human Effectiveness Directorate, located at Brooks City-Base. The next version of the system will be built by the Directed Energy Directorate of the Air Force Research Laboratory located at Kirtland Air Force Base, New Mexico. This newer version will incorporate an eye-safe laser range finder so that the maximum safe laser energy can be placed on target.
