- Abstract
The micro-laser plasma thruster (μ-LPT) is a device aimed at orienting and repositioning small satellites above the atmosphere. These devices are based on IR diode lasers utilized for the ablation of polymers and production of thrust for the control of the satellite motion. In this work, different polymer systems, i.e., poly(vinyl chloride) (PVC), glycidyl azide polymer (GAP), and poly(vinyl nitrate) (PVN) with two absorbers, i.e., carbon nanoparticles (C) and an IR-dye (IR), have been investigated for an application in μ-LPT. The properties of a plasma produced by the irradiation of GAP + C, GAP + IR, PVC + C, and PVN + C with 100 fs laser pulses has been investigated by time-resolved plasma imaging and time and space resolved plasma emission spectroscopy.
