ABSTRACT:
A multi-tip field emission type electron source is fabricated by arranging a multiplicity of micro-size tips so as to be opposedly disposed to a laser active substance composed of an arbitrary semiconductor substance prepared on a conductive substrate, and the space between the two is sealed in vacuum, and the laser oscillation is excited by the electron beams induced by the electric field applied between the two, thereby realizing a solid laser in a simple manner of fabrication. In particular, the invention relates to blue and ultraviolet laser devices using II-VI compound such as ZnSe, or SiC, which were difficult in the prior art.
