Compared with ordinary white light sources (such as sunlight, incandescent lamps, white LED lights, etc.), white laser light sources, short-wave laser light sources and super continuous laser pointer light sources have the advantages of high brightness, strong peak power and wide frequency coverage. Scientific research, national defense and military, lighting, communication technology, information technology, industrial production, biomedicine, environmental testing and other fields have a wide range of practical applications and have received strong attention.
As a brand-new laser light source, white light laser has many advantages such as good directivity, high energy density, super continuous spectrum, extremely wide bandwidth, flexible and diverse center wavelength, high temporal and spatial coherence, etc. Greatly expand the function and application range of laser technology. White light laser or solar laser is completely coherent light in time and space. Not only is the laser beam highly collimated and non-divergent, but it can also focus on a very small area; the amplitude and phase between different colors are completely locked.
By adjusting these amplitudes and phases, the shape of the time pulse of the laser can be changed as desired, and a laser pulse with extremely short pulse width (femtosecond and sub-femtosecond) can be generated. Such a solar laser will make it possible to achieve the dual effect of focusing and concentrating light energy in space and time, releasing energy in a small area and in a very short time, thereby forming extremely high instantaneous power density. As a brand-new laser light source, the application of white light laser covers basic scientific research, communication information, industrial production, national defense and military, biomedical and environmental testing. The brief introduction is as follows:
Basic research in physics, chemistry and materials science. Lasers have been widely used in basic scientific research, including many fields of physics, chemistry, and materials science. The interaction of lasers and substances is required to obtain information about materials in the microscopic world, so as to understand the materials of atoms, molecules, solids, liquids, etc. The state and properties of matter, so as to achieve the goal of understanding and applying the micro world. Unlike the existing conventional green laser pointer, white light laser has the characteristics of super continuous, ultra wide band and completely coherent, so that it can play an important irreplaceable role in many fields beyond the reach of ordinary laser power. The application of this aspect is focused on many research universities and scientific research institutions at home and abroad, and the economic and social benefits are very considerable.
