摘要

Abstract

We briefly review recent results on photoemission spectroscopy based on the deep and vacuum ultraviolet diode pumped solid-state lasers which we have developed. Cascaded second harmonic generation with the nonlinear crystal KBe

(KBBF) is used to generate deep ultraviolet and vacuum ultraviolet laser radiation

which complements traditional incoherent light sources such as gas discharge lamps and synchrotron radiation

and has greatly improved resolution with respect to energy

momentum

and spin of photoemission spectroscopy. Many new functions have been developed with the advantages of high photon energy

narrow linewidth

high photon flux density

and so on. These have led to the observation of various new phenomena and the amassment of new data in the fields of high temperature superconductivity

topological electronics

Fermi semi-metals

and so forth. These laser systems have revived the field of photoemission spectroscopy and provided a new platform in this frontier research field.
