I just cannot confirm which one exist in my process. how can you differentiate between plume behavior and its interaction with laser from the ones with plasma?
Thanks in adnvance

Laser ablation is a process in which a high-energy laser is used to remove material from a solid surface. This can be used for various purposes, such as scientific research, industrial manufacturing, and medical procedures.
When a high-intensity laser is focused on a solid material, it causes rapid heating and vaporization of the surface. This results in the ejection of a plume of vapor and particles. The plasma is created when the vaporized material is ionized by the intense laser energy, forming a highly energetic gas.
A plume is the cloud of vapor and particles that is ejected from the surface during laser ablation. It is made up of neutral atoms, molecules, and small particles. On the other hand, plasma is a state of matter in which the particles are highly ionized and have a high energy level. In laser ablation, plasma is formed from the vaporized material and can be seen as a bright glow surrounding the plume.
Yes, both plume and plasma can be seen during laser ablation. The plume is usually visible as a cloud of vapor and particles, while the plasma can be seen as a bright glow surrounding the plume. However, the visibility of these phenomena may depend on factors such as the laser intensity, material being ablated, and the environment.
Yes, plume and plasma are important in laser ablation as they play a crucial role in the ablation process. The plume carries away the material that has been removed from the surface, while the plasma affects the material removal rate and can also cause damage to the surface. Additionally, the plume and plasma can provide valuable information about the ablation process and the properties of the material being ablated.
