What is a laser ion source?
Some particles and fragments extracted from the target by the laser pulse are electrically neutral, which is why they expand unbiased in the electric field and directly reach the screen placed just on the axis of the system to protect the sample. At the same time, bypass the screen The ions generated by the laser are accelerated by the electric field and focused on the sample located on the axis behind the screen. “The way we choose the field parameters is that only selected ions from the target can reach the sample. The spot diameter of the focused beam is 1 mm,” Rosiński said.

All lasers have a Laser pointer medium, energy source and resonator. The laser medium is a material that can be pumped (excited) to a higher energy state by energy sources such as light or electricity. After pumping, the laser medium can release this energy in the form of monochromatic radiation. The resonator is an area that allows the released energy to accumulate before it is released. The matrix resonant cavity is a pair of mirrors located at both ends of the laser carrier. One mirror is completely reflective, so all the light shining on it is reflected back to the laser medium, and the other side is partially reflected, so part of the light shining on it is reflected back to the laser medium, some of which pass through it and leave the laser
