The patterning process of micro-nano processing is mainly divided into two technologies: pattern transfer and direct processing. The pattern transfer technology includes three parts: thin film deposition, pattern imaging, and pattern transfer. The direct processing laser pointer beam etching technology has the ability to write directly, avoiding the multi-step process of pattern transfer, by controlling the focused…

The laser pointer reflected between the earth and the moon promotes development
Since 2009, NASA’s Lunar Reconnaissance Orbiter (LRO) has orbited the Moon more than a dozen times a day. There are 6 high-tech instruments on the Lunar Reconnaissance Orbiter. These 6 high-tech instruments not only help scientists draw detailed maps of the moon, but also give them a better understanding of the radiation and temperature on…
Physicists photographed crystal structure transformation under laser pointer beam
Laser beams can be used to change the properties of materials in extremely precise ways. This principle has been widely used in technologies such as rewritable DVDs. However, the basic process is generally carried out at such an unimaginable speed and such a small scale that it has not been directly observed so far. Researchers…
Research and development of carbon nanotube materials for infrared laser pointer systems
The ultrashort pulses of light generated by fiber laser pointer have promoted major advances in the fields from biomedicine to micromachining. Compared with systems based on traditional semiconductors, the development of carbon nanotube materials for products can bring important advantages. Carbon nanomaterials, such as carbon nanotubes (CNT), have unique optical properties and can be optimized in a…
Laser pointer welding is mainly used for thin metal materials
Laser precision cutting laser, with good beam quality, less heat effect in the cutting seam, no heat deposition, smooth cutting edge and no burrs; high peak power (>15kW), fast cutting speed, flat cutting material and not easy to deform. Pulsed fiber laser pointer welding is mainly used for spot welding and seam welding of thin metal materials….
Five applications of ultra-stable pulsed fiber laser pointer
The birth of pulsed laser technology is an important breakthrough in the history of laser pointer development. It has been widely used in many industries and has made great contributions to the upgrading of manufacturing and the promotion of laser technology. Laser has a profound technological accumulation in the field of pulsed fiber lasers. At present, it…
The laser pulse can make good contact with the silicon surface
Draining current from the wafer requires many small holes in the non-conductive layer to allow the metal electrode to contact the silicon wafer. The LFC process enables nearly 100,000 contact points on the wafer to establish a connection with a single laser pointer pulse. The biggest difficulty of this work is that the laser pulse can form…
New laser pointer manufacturing process revolutionizes the photovoltaic market
The Solar Energy System Research Institute in Freiburg, Germany has developed a laser pointer-based manufacturing process method that is revolutionizing the photovoltaic market. Mass production of point-contact solar cells was realized for the first time. Millions of batteries with high efficiency levels have entered the market. In the next few decades, one of the main challenges…
Combination of standard laser pointer dyes
In recent years, when the graphene industry is booming, another new type of single-element two-dimensional atomic crystal material-black phosphorus has been discovered. Similar to graphene, black phosphorus has many excellent properties, so it is called a “dream material” comparable to graphene. Its nonlinear optical characteristics have been confirmed by many domestic and foreign companies and…
Different types of lasers are built on silicon materials
Building a quantum cascade laser on silicon is extremely challenging, mainly due to the strong absorption of SiO2 in the long-wavelength mid-infrared band. “This means that we not only need to build different types of laser pointer on silicon materials, but also different types of silicon waveguides.” The project leader said: “We built SONOI waveguides and used…
