| Abstract: | The temperature distribution and deflection of a high power laser silicon mirror are predicted numerically by the finite difference method when its boundary is kept insulated.It is shown how the deflection of a mirror varies with laser power,optical spot diameter,mirror thickness and how its temperature distribution and deflection change with laser run time. |

| Keywords: | high power laser silicon mirror deflection |
