  With the optical kerr effect, the conventional photonic crystal can be turned
into the function photonic crystal under the action of pump light. In the
paper, we have designed the ultra-strong light source and laser with
one-dimensional function photonic crystal. When the incident light is the
ordinary light, the output is ultra-strong light source, and when the incident
light is the low power laser, the output is ultra-strong laser, the maximum
magnification can be reached $10^{80}$ and even more. Otherwise, we analyzed
the effect of period number, medium refractive index and thickness, incident
angle, the pump light irradiation way and pump light intensity on the
magnification, these results shall help to optimal design ultra-strong light
source and laser.
