Measurement of radiative properties of pulsed laser induced plasma
- Purdue Univ., West Lafayette, IN (United States). School of Mechanical Engineering
When high power, pulsed lasers are utilized in materials processing applications such as machining and pulsed laser deposition, plasma is generated by laser irradiation. Analysis of the energy transport process between the laser and the target is complicated by laser-induced plasma layer which mediates between the laser and the target. This work investigated the transient radiative properties of the laser-induced plasma. Novel diagnostic technique was developed to measure the transient transmission of the plasma layer, whole thickness varies between a few micrometers and a few hundred micrometers within the pulse duration. The transmissivity of plasma obtained from this study helps to understand the energy transport mechanism during high power, pulsed laser interaction with materials and quantifies the energy coupling efficiency between the laser and the target.
