Lasers less ordinary
Laser technology is firmly anchored in many industrial applications. Examples range from laser welding in battery production and laser cutting of sheet metal in mechanical engineering to the marking of components in assembly and laser drilling of needles in medical technology.
In addition to these well-known applications, there are plenty of new possible uses for which laser technology paved the way. Made by Laser presents the most stunning examples.

From surface to space – this is the theme, the artist Susanne Specht realized with Matthias Schrader, technician at the Laser Zentrum Hannover e.V. (LZH), with large format paper. While she had worked with a small laser cutting instrument before, at the LHZ she could cut papers with a length of 2 to 3m.
In two intense work days, several long format paper works were created. Suspended freely in the room they become sculptures to be looked at from all sides, opening new perspectives all the time depending on the location of the spectator. Delicate lines point through the cuts to the “behind” in three dimensional space, smoke traces underline the powerful line design and individual elements seem to bend forward or backward at points where directions change or run opposite, creating a minimal spatiality.
A safe and sustainable labelling alternative with a positive CO2 footprint for retailers and the food industry:
In the natural branding process, a cold marking process, a blue laser light system removes the top pigment layer of the natural skin of the food and impregnates the desired lettering directly onto the food by means of a focused light beam. The advantages: high absorption, good processing efficiency and low energy output AND without any loss of freshness, fragrance, taste, aroma, or shelf life. And best of all: With natural branding, retailers can save tons of plastic and significantly improve their CO2 emissions.

Fraunhofer IWS and Papiertechnische Stiftung PTS are jointly creating the basis for a binder-free paper joining process. The novel process of combining laser irradiation with high-energy, short pulses of a CO laser and subsequent hot pressing allows, among other things, the production of corrugated board that can be easily recycled.
In the past, fouling on maritime surfaces was mainly treated with coatings and mechanical cleaning albeit with only moderate success. Environmental damage often had to be accepted, not to mention the damage to surfaces. A new process using Laserline’s blue diode lasers could now change all this. This is currently being tested in Helgoland.
Scientists are researching how changes in cell cultures of cartilage and soft tissue can be detected in a cooperative research project. The principle relies on a "white light laser".
Nowadays, glasses are no longer just a visual aid, they are a fashion accessory. Premium eyewear manufacturer Silhouette knows all about this and uses laser technology in production.
In terms of new environmental protection efforts, the reduction of CO2 emissions along with the reduction of fine dust is an important goal. New high-speed laser technologies make it possible to manufacture a new generation of brake discs.
Chemical weed control - keyword Glyphosate - is widespread but often encounters harsh criticism for its effects on the environment. The alternative for a weed-free soil? Laser!
The pharmaceutical industry uses chicken eggs as sterile “nutrient containers” to breed viruses for live vaccination. For a long time, the eggshells were cracked manually. Today, the delicate calcareous shell is opened by laser.
After the IFSW Institute of Jet Tools at Stuttgart University already invented the Laser Raclette, it took on the French dessert classic Crème Brûlée that can now be produced in large quantities with laser.
