The difference between white laser pointer and ordinary laser pointer
Existing laser technology has always had a drawback, that is, only a single wavelength or narrow band of light. How to enlarge the frequency of red laser designator to form ultra-wideband, ultra-continuous, phase dry white laser covering ultraviolet, visible and infrared 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 the natural laser crystal material has a large margin in the gain frequency range and gain bandwidth, the laser cannot produce green laser pointer of any wavelength. Existing laser technology, however, has been plagued by the fact that it emits only a single wavelength or narrow band of light. How to expand the laser frequency to form ultra-wideband, ultra-continuous, coherent white laser covering ultraviolet, visible and infrared bands is still an unrealized dream and a worldwide scientific and technological problem.

Existing laser technology, however, has been plagued by the fact that it emits only a single wavelength or narrow band of light. How to expand the laser frequency to form ultra-wideband, ultra-continuous, coherent white laser covering ultraviolet, visible and infrared bands is still an unrealized dream and a worldwide scientific and technological problem. This is because the high powered 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 the gain frequency range and gain bandwidth, a 5MW laser designator cannot produce lasers of any wavelength. Laser is the 20th century after atomic energy, computer, semiconductor, human beings another major invention. The combustion laser designator has the characteristics of good orientation, high brightness and good monochromism. Its comprehensive performance far exceeds the traditional fluorescent lamp, incandescent lamp, fluorescent lamp, LED lamp and so on. It's a revolutionary way of harnessing the information and energy of light. Laser technology has come a long way in the past 50 years since Mayer invented the first laser (the ruby laser) in 1960, achieving great success and playing an important role in many areas of human society.
