Most engineers are familiar with the basic laser pointer physical parameters that need to be measured, such as temperature, pressure, position, speed, and distance. But there are other key parameters that are also very important. An example of this is the measurement of light refractive index (RI), which is also part of many liquid processing processes, such…

Since Mayman invented the first laser pointer (ruby laser) in 1960, laser technology has achieved tremendous development and great achievements in the past 50 years, and has played an important role in many fields of human society. . The development of laser technology is changing rapidly, from the early gas laser (He-Ne laser), high power carbon dioxide…

Thanks to the improvement of people’s consumption level, the market demand for home theaters continues to rise, and the laser theater concept has become very popular nowadays. Traditional home appliance brands such as Changhong and Hisense have been deployed early, and Internet brands have also actively entered the market. The much-anticipated M brand laser pointer laser projection…

Cambridge researchers have discovered a breakthrough “recipe” for inkjet printing that can enable mass production of next-generation laser pointer and optoelectronic technologies. A study led by a PhD from the Graphene Center of Cambridge University found that black phosphorous ink is a unique two-dimensional material similar to graphene, compatible with traditional inkjet printing technology, making it possible…

White light lasers have characteristics that traditional lasers do not have, making up for the shortcomings of traditional lasers; the research and development of white light laser pointer light sources can bring more fields of change and development, and generate new scientific fields and new applications; therefore, it is inevitable Become the object of many scientists chasing…

First of all, the real white laser pointer should have all the laser characteristics of the traditional laser except monochromaticity, and it should also have the excellent characteristics that the traditional laser does not. Secondly, the white laser light source is white light, so its spectrum must be consistent with the spectrum of sunlight incident on sea…

Medical laser products provide unique applications for the gynecology field; the gynecology field is expected to become a major driving force for the further growth of the medical laser system market in the next five years. At the same time, the system is also widely used in gynecological abdominal surgery, so it will further promote…

What types of laser surgery are included? Some common laser surgeries include: refractive surgery (commonly known as excimer laser surgery-LASIK); teeth whitening; scar beauty, tattoo or wrinkle removal; cataract or tumor removal. Different surgeries use different lasers. For example, carbon dioxide (CO2) laser pointer is used for shallow cutting. They are usually used for the treatment of…

Laser treatment is the use of laser pointer beam for disease treatment. In medicine, surgeons can perform high-precision operations with lasers, concentrating the light beam on a small area, thereby causing less damage to surrounding cellular tissues, and achieving therapeutic purposes. Compared with traditional surgery, the use of laser treatment will reduce pain, eliminate swelling and scar…

Technically speaking, at present, traditional lidar technology is very mature, and solid-state lidar and hybrid solid-state lidar are still in their infancy. Therefore, the laser lidar used by companies in self-driving cars is mainly based on mechanical laser pointer radar. From the perspective of the entire lidar industry, manufacturers of high-precision automotive lidar products are mainly concentrated,…
