摘要
基于傅里叶热传导方程, 利用有限差分法计算了石英在激光作用下的温度场分布。结果表明在连续激光的作用下, 石英的轴向温度变化分为升温过程和降温过程。考虑热累积效应, 辐照0.1、0.5、0.8 s后温度较之前分别升高了约 10、100、200 ℃, 激光作用时间越长, 温度累积越明显。对于脉宽为5 ms, 占空比为1/2和1/3的脉冲激光, 辐照3个脉冲后, 温度分别升高94 ℃和82 ℃。石英在轴向方向的温度累积较径向更明显。研究激光与石英相互作用后温度场的分布对激光加工工艺有着重要的意义。
Abstract
Based on the Fourier heat conduction equation, in this paper, the temperature field distribution in the interaction of laser and silica is calculated by using finite difference method. Irradiated by CW laser beam, it indicates that temperature distribution of silica along the axial direction include heating and cooling process.Considering the cumulative effects of heat, temperature rise respectively about 10, 100 ℃ and 200 ℃ than before, after irradiating 0.1、0.5 s and 0.8 s. The cumulative effect of temperature in the silica is markedly enhanced with the increasing of reaction time. For the pulse laser with pulse width of 5 ms and duty ratio of 1/2 or 1/3, Temperature rise 94 ℃ or 82 ℃ respectively after irradiating 3 pulses. And such cumulative effect of temperature along the axial direction are much more obvious than the radial direction. Temperature distribution in the interaction of laser and silica has significant implications in laser-machining techniques.
