| 摘 要： | 研究了同心分区偏振偏转相位板对径向偏振光梯度力的调制效应。给出了相位板各部分偏振偏转角不同时，光学梯度力的分布情况。模拟结果表明:随着同心分区相位板各部分的半径和偏振旋转角的改变，光学梯度力方向及大小明显变化，且会产生许多可控的梯度力分布模式，可应用于微粒的收集、分离和合并。结果显示同心分区相位板对径向偏振光的调制可以用来生成可调光镊。

| Abstract: | The gas circulation system in TEA CO2 laser is very important. The parameters, the structure and the design of the system are analyzed. A symmetric structure is adopted and an axial blower and a plate-fin heat exchanger are selected. Using volume flux method, the gas velocity in the discharge zone is determined. The static pressure parameters of the fan are determined, taking into account of the additional resistance.The gas circulation system has an average gas velocity of 84.8 m/s, with inhomogeneity 4.2% longitudinally and 0.38% horizontally respectively. Under the condition of a discharge volume of 2.5×10-3 m3, a single pulse injection energy of 276 J, and a discharge pulse width at 150 ns, the system successfully achieves an even and steady glow discharge at a repetition rate of 400 |
