Laser Induced Plasma Assisted Ablation (LIPAA) has the advantages of economy, environmental friendliness, and high efficiency in the preparation of glass surface metallization. The feasibility of realizing metallized pattern circuit by using LIPAA process on glass substrate with metal copper as sacrificial target under nanosecond laser is studied. Therefore, firstly, the conductivity of metallized pattern circuit on glass substrate prepared by progressive scanning LIPAA is discussed in detail. In view of the disadvantage of the reduction of its conductivity caused by oxidation, the hydrogen reduction was further used to optimize its post treatment, and the circuit performance was analyzed by combining Scanning Electron Microscopy(SEM) and Energy Dispersive Spectroscopy (EDS), revealing the morphology characteristics and the change rule of resistivity of the surface of the glass metallized pattern circuit prepared by nanosecond laser LIPAA method. The results show that the metal layer on the glass surface can be directly ablated by the laser patterning removal process, and the fine patterned circuit can be prepared on the glass surface. At the same time, the chemical hydrogen reduction method can overcome the disadvantage that the metal layer oxidation seriously affects the circuit resistivity. The average resistivity after chemical hydrogen reduction is only 8.18 X 10-7Ω·m, which greatly improves the conductivity of the patterned circuit on the glass surface, shows broad application prospects.

A nanosecond pulsed laser ablation platform of SiC material and a nanosecond pulsed laser induced plasma experimental system were established. One dimensional fluid mechanics code was used to simulate the dynamic process of plasma jet generated by high power laser during the ablation of SiC material. The nanosecond pulsed laser ablation rule of SiC material was obtained, and the effect of laser induced plasma on ablation depth was verified through experiment and numerical simulation. The research results can provide reference for material engineering applications related to nanosecond laser ablation. [ABSTRACT FROM AUTHOR]

In order to choose an appropriate perforation for improving the quality of slim cigarettes, effects of online laser, off-line laser, plasma and static electricity perforations on filter ventilation efficiency, filter ventilation rate stability and sensory quantity for slim cigarretes were investigated. The results showed that all of the four perforations could meet the design needs of filter ventilation rate. Higher filter ventilation rate could achieved of slim cigarettes perforated by plasma and static electricity when air permeability of tipping paper was fixed. Filter ventilation rate stability of slim cigarettes perforated by plasma and online laser was better comparatively. It was more beneficial for improvement of sensory quantity of slim cigarettes perforated by plasma and online laser. Sensory quantity of slim cigarettes perforated by these two ways was corresponded when the filter ventilation rate was lower, and that perforated by online laser was superior to perforated by plasma when the filter ventilation rate was higher. In conclusion, plasma and on-line laser perforations were better than static electricity and off-line laser perforations as a whole, and were the preferred punching methods in the prduction of slim cigarette.

Considering the structural characteristics of space one-dimensional deployable truss, a precision measurement method for the space one-dimensional deployable truss structure is presented. The measurement method is based on spot center position detection principle of quadrant detector, and collimated laser beam is used as Measuring Datum. Using this method, the torsional angle, lateral deviation, vertical deviation of each truss bay in the truss and the truss straightness can been measured. Two-dimensional plane calibration method of the quadrant detector is presented, and working range of the quadrant detector is enlarged to 3 mm x 3 mm, measuring accuracy of the quadrant detector is improved to 0.05 mm. Precision of the space one-dimensional deployable truss is measured based on quadrant detector. The maximal torsional angle of the truss bay is measured to be 0. 133 3°, the maximal lateral deviation and vertical deviation of the truss bay are 1. 200 8 mm and 1. 099 3 mm respectively, and the truss straightness is measured to be 1. 090 6 mm. The precision measurement test of the space one-dimensional deployable truss verifies the effectiveness of the method presented. [ABSTRACT FROM AUTHOR]
