However, the existing laser technology has always been short plate, that is, can only emit single-wavelength or narrow-band light. How to enlarge the frequency of laser, form ultra-wideband, ultra-continuous, covering the ultraviolet, visible and infrared bands of coherent white laser 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 material has a large margin in gain frequency range and gain bandwidth, the 5 mW laser indicator can not produce any wavelength laser.
