These high-power fiber lasers are standard tools for metal laser cutting and welding in the macro application branch. The standard cutting system is usually equipped with a compact fiber laser pointer. Depending on the power of the cutting system and the thickness of the sheet, it is equipped with a direct processing fiber with a core…

Heat-affected zone for better laser pointer processing quality
Collect the back reflection light in the isolator and monitor it with a photodiode. The real-time output of the sensor is provided to the user for use in process monitoring, optimization and control (such as perforation detection), or tool calibration (such as beam position and focus). Other characteristics of laser pointer outlined include improved cutting and welding…
South Korean researchers develop new laser pointer device to prevent food poisoning
As the number of food poisoning cases has gradually increased, South Korea has begun to implement relevant measures. It is understood that Korean scientists have developed a laser pointer to find bacteria on the surface of food. Researchers at the Korean Academy of Advanced Sciences have developed a red laser beam that is scattered on the surface…
Kilowatt fiber laser technology has matured
Fiber lasers combine active (laser gain) fiber with one or more pump lasers (usually laser diodes). There are many types of fiber laser pointer, including low-power continuous (CW) lasers, low-energy and high-energy pulsed lasers, including ultrafast fiber lasers. But when it comes to fiber lasers, many people may think of only kilowatt continuous fiber lasers. This…
Optical fiber obtains single-mode or multi-mode laser pointer beam quality
Rofin produces CW high-power fiber lasers (FL series) with output power between 500 and 8000W, and provides a variety of solutions to irradiate the laser pointer output light to the workpiece. The company’s lasers can be equipped with direct fusion spliced fibers to obtain single-mode or multi-mode beam quality; or equipped with fiber-to-fiber couplers or fiber-to-fiber switches…
Provides significantly higher laser pointer power through a single beam
The single-mode YLS-2000-SM laser with a rated power of 2kW can process iron (Fe) and aluminum (Al) parts. It is easy to adapt to handle parts with different diameters and grooves of different depths (up to 30μm). The maximum power consumption is 5.5kW. Different groove angles can also be achieved. The quality and productivity of…
A specific case of single-mode laser pointer application
The same multimode YLS laser is used for high and low brightness applications, such as welding, drilling, and precision cutting-an unprecedented capability. The high brightness allows the use of telephoto processing lenses, which are used to greatly improve the depth of field and minimize the damage to the optical components. Although high-brightness multi-mode laser pointer dominate the…
The power-driven laser pointer has many advantages
The Navy uses expensive weapons and ammunition to strike back at targets—they are incoming missiles, small assault boats, and coastal defense systems—even if these targets are destroyed, it will only cost the enemy very little. Said at a seminar at the Marshall Institute. “This is not an affordable game. If you need to continue this…
The U.S. military studies the use of laser pointers against missiles
The US “National Defense” magazine published an article by Dan Parsons, briefly introducing the US military (mainly the Navy) is studying the use of various low-cost laser pointer to counter enemy missiles and other weapons. In order to maintain its technological superiority, the U.S. military has invested more money in this area than any other country’s military….
How did the reflective ultra-short throw laser projection evolve?
How can the projector overturn the TV? If you look at the performance of traditional projectors, there are actually many shortcomings. The first is the problem of the laser pointer. The traditional projector lens needs a long distance to achieve a large screen, so users need a lot of space to use. Therefore, many meeting rooms…
