Laser-based angle-resolved photoemission spectroscopy (ARPES) is an advanced experimental technique used primarily in condensed matter physics to investigate the electronic structure of materials. It combines the principles of angle-resolved photoemission with the high energy and specificity offered by lasers. \#\#\# Key Features of Laser-based ARPES: 1. **Photoemission Principle**: In ARPES, photons are used to excite and eject electrons from a material's surface.
