Summary
Switching of argon gas discharge is controlled by metal plasma or target polarity when using laser-produced plasma. This study investigates laser-produced plasma interactions with biased metal targets in argon gas.
Area of Science:
- Plasma Physics
- Laser-Material Interactions
- Gas Discharge Physics
Background:
- Laser-produced plasma (LPP) is a key area of research.
- Understanding LPP interactions with background gases and biased targets is crucial for applications.
- Argon gas discharges are common in various industrial and scientific processes.
Purpose of the Study:
- To investigate the influence of a biased metal target on laser-produced plasma.
- To determine the control mechanisms of argon gas discharge switching by LPP.
