A photon with the correct wavelength to be absorbed by a changeover also can induce an electron to fall from the higher on the reduce degree, emitting a different photon. The emitted photon precisely matches the original photon in wavelength, stage, and course. This process is called stimulated emission. เครื่องเลเซอร์มาร์คกิ้งแบบใช้มือถือ https://archimedesk307wzc8.wikififfi.com/user
