Optical systems are susceptible to saturation or damage caused by high power lasers. The major issue is to find a mechanism to protect from laser threats without interfering with the optical system performances. This paper presents a new approach in exploiting the laser energy itself to enable a dynamic response of a protection filter. We discuss an up conversion mechanism in which two or more photons of the threatening laser are absorbed by an up converting molecule following an energy transfer to a molecule that is able to change its absorption spectra and absorb in that laser wavelength range, thus creating a dynamic filter limiting high power lasers while allowing high transmittance for low intensity light.
