By collecting these optical information, information on their component distribution and Fengdu can be obtained, helping the environmental protection department to grasp in-depth and detailed atmospheric composition information and give corresponding countermeasures. The ordinary laser pointer radar uses a monochromatic laser as a detection source, which can only generate strong scattering effects with specific atmospheric molecules, while super-continuum, ultra-wideband, high peak power white light lasers can interact with multiple atmospheric molecules at the same time. The one-time light scattering information will be extremely rich, so it will greatly improve the lidar’s ability to monitor atmospheric quality.
Laser has been widely used in laser processing (cutting, welding, manufacturing and 3D printing, marking), information technology (laser anti-counterfeiting, holographic information storage, laser color display, laser TV, laser projector), sensing and detection, communication ( Optical fiber communication, free space optical communication, visible light communication), etc. As a new product, white light laser will have its unique industrial application field.
Color holography: Laser holography is a very widely used technology for recording and reproducing object shape information. Its principle is to use the interference effect of laser (refer to the interference of laser light and object reflected laser). In principle, all objects can be recorded. Information (visual brightness information (ie, reflection amplitude information) and phase information). Typical applications are laser anti-counterfeiting and laser scanners (barcodes used in ultrasound). Ordinary holograms use monochromatic lasers to generate holographic fringes. If color lasers or white light lasers can be used to generate holographic interference fringes, in principle not only can reflect the Outline information, and can reflect color information.
This is a true all-round information recording and reproduction technology of objects. This technology not only greatly improves the amount of information contained in the hologram, improves the reliability of laser anti-counterfeiting, and increases the difficulty of information cracking, but also can truly reproduce the three-dimensional information and color information of objects. 3D display and virtual reality technology: the use of white light green laser pointer can realize color holography, realize the recording and reproduction of 3D information of objects. Therefore, it is expected to be applied to 3D display and virtual reality technologies that are widely concerned in today’s society but have not made progress due to technical difficulties.Using white light laser pointer to illuminate color hologram
In actual operation, you can refer to the technology of the film industry, record the images and information of moving objects on the film, record at the rate of 16 frames per second, and play at the same speed, you can easily achieve filming and filming Two processes. The same is true for color holographic 3D display, except that the 3D image of the object (color and contour information) is stored on the color hologram at 16 frames per second, and then the white light laser pointer is used to illuminate the color hologram at 16 frames per second, which can be played Produce images with fully realistic 3D color effects. Combining such technology with virtual reality technology and augmented virtual reality technology is expected to be a true-color 3D virtual reality technology.
The laser is both a carrier of information and a carrier of energy. Both features can find numerous applications in the defense and military fields. As a carrier of energy, the laser can be used to manufacture active infrared imaging and night vision devices, or it can be used as a laser weapon with high directional energy for laser confrontation. In addition, the principle of photoelectric effect can also be used to produce laser damage and destruction to the optically sensitive parts of enemy satellites, missiles, aircraft and other flying objects by using small and medium-energy lasers, thereby achieving the purpose of destroying enemy military targets.
In this regard, supercontinuum, ultra-wideband, high-power white light lasers have unique advantages because of the large frequency window of the photoelectric effect, it is easy to physically perform a variety of optically sensitive devices (usually an optical device has a sensitive wavelength) And chemical reactions. In addition, the peak power of the white light laser is huge. When it interacts with the optically sensitive device in resonance, it will produce a huge destruction effect. This technique is especially suitable for jamming and destroying enemy satellites.
As a carrier of information, green laser pointer can be used for free space communication, especially for areas that cannot be reached by optical fiber communication, such as space and the interior of the ocean. Because white light laser has a wide band, as a communication tool, the amount of information contained can be much larger than that of ordinary monochromatic laser, so it is especially suitable for free space laser communication between submarines inside the ocean.
