The influence factors of energy transmission and energy loss in optical fiber ar e analysed. The factors include the material, the structure, the refractive index distributing, the length, the diameter, the num erical aperture,thermal effect and the coupling of optical fiber. The significa nce is simultaneously analyzed using laser diode ignition as the example. The co nclusions are that it is indispensable to select the appropriate laser wa velength, the shorter length, the smaller laser diameter, the less numerical ape rture, using the graded index optical fiber, and the less bends and couplings fo r decreasing the energy loss and increasing the deferent laser powerdensity.
