Abstract

To monitor the environment in high peak laser system inline, the method to sense containments by using optical microfiber(OM) was proposed. To realize precise control of the OM diameter, we firstly analyzed the OM fabrication process, obtained the relationship between the deviation of the OM shape and the errors of heating length and stretching length, then simulated the deviation in different situation, finally got the optimal parameter to fabricate OM with the length of 10 mm and the diameter of 1.5 m. We have proved the simulation results by measuring the shape of the drawn OMs. According to our research, precise control of OM shape can be achieved by tuning the OM fabrication parameters, and the results lay the foundation for practical application of OM contaminants sensor.
