The existing laser technology has always been short plate, that is, only a single wavelength or narrow band light. How to expand the frequency of red laser to form ultra-wideband, ultra-continuous, ultraviolet, visible and infrared coherent white laser bands is still an unrealized dream and a worldwide scientific and technological problem. This is because the laser consists of an optical resonator, a gain medium and a pump source. The wavelength of the laser is determined by the energy level structure of the atom, molecule or ion in the gain material. Because natural laser crystal materials have a large margin in gain frequency range and gain bandwidth, laser can not produce any wavelength laser.
