Three-Dimensional Temperature Distribution Analysis and Thermal Lens Effect Calculation for High Power Laser Windows
Heat absorption of high power laser windows is analysed and the heat equation of the window for practical working device and its solving condition are given. Physical state of the high power laser is simplified suitable for the pratical condition. Analytic solution of the heat equation is given. Then the thermal lens effect of high power laser windows is calculated considering the thermal changes of refractive index of the window material and linear expanding index, and the result is disscussed.
