excimer laser features
1. The excimer exists in the form of an excited state, with a short life span, only 10^(-8)S magnitude, and the ground state is 10^(-13)S magnitude. The transition occurs in the low excited state and the repulsive ground state (or (Weakly bound), the fluorescence spectrum is a continuous band.
2. Since its fluorescence spectrum is a continuous band, it can realize wavelength tunable operation.
3. Due to the rapid dissociation of ions in the lower energy level (ground state) of the laser transition, the lower energy level of the laser is basically empty, and it is easy to achieve population inversion, so the quantum efficiency is very high, close to 100%, and it can operate at a high repetition frequency. .
4. The output laser wavelength is mainly in the ultraviolet to visible light range, with short wavelength, high frequency, large energy, small focal spot, and high processing resolution, which is more suitable for high-quality laser processing.
