Title:
LASER COAXIAL ION EXCITATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/159861
Kind Code:
A1
Abstract:
A laser coaxial ion excitation device, comprising a light path center and an ion transmission channel. The light path center is hollow, the light path center is coaxial with the ion transmission channel, the ion transmission channel is perpendicular to a matrix carrier, laser focusing light spots are focused in a non-uniform way, and a light path comprises but is not limited to a laser transmission light path, a visual monitoring light path, a visual illumination light path and a light intensity monitoring light path. The laser coaxial ion excitation device is reasonable in structural arrangement, wide in ion mass range, high in resolution and capable of effectively improving ion excitation abundance.
