| Popis: |
The response characteristics of a Fiber Bragg Grating(FBG) irradiated by high energy laser beams are investigated both theoretically and experimentally to explore the possible applications of the FBG to High Energy Laser(HEL) parameter measurements.The thermal response characteristics of the FBG irradiated by HEL beams are obtained by solving the heat transfer equation using certain approximations.The resonance wavelength information of the FBG is recorded with an interrogator.The experimental results show that the maximum resonance wavelength shift of the FBG changes linearly with the irradiating power density within a certain range,which agrees with the results of numerical simulation. |
