Teach you how to avoid the laser “heavy cold”

The autumn wind is blowing, the winter is approaching, the miles are frozen, and the snow is floating. In the cold winter temperature conditions, if you don’t have careful maintenance, the laser working hard day and night may also have a “heavy cold”: when the ambient temperature drops below the freezing point, the coolant in the laser will change from liquid to solid. The volume of solid coolant will increase significantly, which will create the risk of rising water [...]

Two-step laser mass spectrometry for more accurate cell research

It is reported that in order to improve mass spectrometry to enhance the study of cytochemical composition, researchers from the University of Münster have developed a method for improving the spatial resolution of matrix-assisted laser desorption ionization (MALDI) mass spectrometry in UK health agencies. Increased by about a thousandth of a millimeter. The researchers called the technique t-MALDI-2 (‘t’ indicates the transmission mode), which uses two lasers: one for generating a smaller focus on the removed material and the other [...]

Laser ultrasound provides a new way of thinking for nondestructive testing

Many industrial buildings, including nuclear power plants and chemical plants, rely on ultrasonic instruments that continuously monitor the structural integrity of their systems without damaging or changing their function. Currently, scientists have developed a new technology that uses laser technology and candle soot to generate effective ultrasound for non-destructive testing and evaluation. A group of researchers are currently using Ultrasonic Nondestructive Testing (NDT), which involves amplification of photoacoustic laser source signals using a nanoparticle array of candle soot and polydimethylsiloxane. [...]

Laser Engraving Marking Machines with Different Precision Ruler Configuration

What Kind of Precision Ruler of a Fiber Laser Engraving Marking Machine Should We Choose?

About the precision ruler of a fiber laser marking engraving machine, it is used to measure the precise focusing of the laser working on the surface of the material need to be processed. It is a very simple and unimpressive. Actually, it is really not as important as some core components like optical galvo scanner & lens and fiber laser source. But in some especially situation and circumstance, it has a remarkable role. First, Let’s take a look at the [...]

What Laser Marker Engraver Should We Choose If Mark Engrave 200 x 200mm Area?

As we know, the normal configuration of a fiber marker engraver is 20W power with 110 x 110 mm lens. Usually, the marking engraving within 110 x 110 mm area is enough for most kinds of laser marking engraving application needs.                      Laser Marker Engraver 110 x 110mm But a few customers need to engraving marking some bigger patterns or logos sizes than 175 x 175 mm or 200 x 200 mm, even [...]

What are the Differences of Raycus, Super, Ipg and Max Fiber Laser Source?

A fiber laser engraving machine system must need to equipped with a fiber laser source. There are various kinds of brands, for example, Raycus fiber laser source, Super fiber laser source, IPG fiber laser source, Max fiber laser source. Let’s compare their function and character differences. Raycus fiber laser source The Raycus fiber laser source is famous for its stability and high performance. Its performance is excellent, but its cost is also not cheap. So If you want to buy a true [...]

What is the Source for the CO2 Laser? is it Air Cooled?

The Laser source of Co2 laser has two kinds of types, one is Metal Co2 laser tube source, another is Glass Co2 laser source. The metal laser source is sealed by the metal case, it is composed of high precision and high tech structure workmanship. So it has a high precision and high-performance laser processing, including laser engraving/marking/etching/carving, laser cutting etc. the Metal Co2 laser source also can be called RF(Radiation Frequency) Co2 laser source. The Metal Co2 laser source’s [...]
