Oscillatory disturbance in force calibration of optical tweezers

In the calibration of the optical trap stiffness, it is found that there appears an attenuating oscillation as an oscillatory disturbance added to the trapped bead movement, when the scanner is driven by a triangular wave input.An equivalent oscillator model is put forward to explain the mechanism of the oscillatory disturbance. Both the measurements and calculations show that the attenuating oscillation comes from the oscillation of the scanner and the triangular wave drive causes this additional oscillation of the scanner. Furthermore, the analysis indicates that the oscillatory disturbance will become stronger, when the stiffness of the trap increases or the natural frequency of the scanner decreases. We adopt another driving way, i.e. a sinusoidal wave input is used instead of the triangular wave input. Our experiment has verified that in this case the oscillatory disturbance is eliminated completely.

Generation of a Collimated Doughnut-Beam for Atom Trapping Using a Single-Cone Axicon

We propose a novel method to generate a collimated doughnut-beam (DB) using only one single-cone axicon andrealize it experimentally. The diameter of the DB is estimated by ray optics and is in good agreement with theexperimental results. The CUD image of the DB and the radial light intensity distribution are experimentallyobtained. The light intensity of the DB dark inner region is about 1% of the peak intensity of the DB. Thefar-field divergent angle is about 6mrad and seems to be well-collimated. With optimum values of the power andthe positive detuning of the laser field, the optical dipole potential of the DB can be chosen to be very large as agood confinement for atom trapping.

光度法快速测定化学需氧量的催化剂研究

化学需氧量(CODCr)是衡量环境污染的重要指标，CODCr测定的标准方法为重铬酸钾法，但这种方法操作繁琐，耗时较长，且消耗药品较多。虽也有多种改进方法，有的仍要滴定操作，或使用昂贵的Ag2SO4作催化剂。本文是在吸光光度法快速测定CODCr简化操作的基础上，选用MnSO4／CuSO4作为混合催化剂，其准确度和精密度较好，适用于工业废水CODCr的测定。
