Without the rare earths of China, lasers will end in Europe. Germany has found a way to do without them

The applications of Rare earths They are potentially unlimited. To this peculiar group of chemical elements belong some metals as elusive and with names as suggestive as neodymium, promised, gadolinium, ititrium or scandio, among others. Some of them They are relatively scarceand, in addition, they are not usually found purely in nature, but what makes them so special are their physicochemical properties.

Its characteristics are beyond the reach of the other elements of the periodic table, which has caused that during the last decades they are consolidated as A very valuable resource In numerous industries, especially in electronics and renewable energies. They are involved, for example, in the manufacture of hybrid and electric cars engines, batteries, semiconductors, catalysts, optical fiber, LCD panels, and even in wind turbines.

Europe wants to stop being in the hands of China once and for all

China dominates the rare earth industry with an indisputable forcefulness. According to him US Geological Service For many years it has produced more than 90% of this valuable resource. In 2022 its market share was reduced to 70%, but did not do so because of a decrease in production; This fall had its origin in the increase in rare earth production quota experienced Australia, Vietnam and Myanmar, among other countries.

In addition, the country led by Xi Jinping also dominates the processing industry to which it is necessary to submit rare earth so that they can be used. So much so that according to Xincaifu Its quota if we expressly stick to the global processing industry ascends 90%. And with a 70% production of the global market and a 90% control of the Chinese rare earth processing industry has this absolutely controlled market.

The government of this Asian country is using its control of these chemical elements to defend their strategic interests In full confrontation with the US, Europe and its allies. In this context, the old continent needs to bet on its independence and the consolidation of its own supply chain. And it is in it. In fact, Germany has just made a very important contribution in a scenario of fundamental use of rare earths: the manufacture of lasers.

These devices are used to produce medical equipment, in scientific research, in the manufacture of consumer electronics, and even in the tuning of Quantum computersamong many other industries. Rare earths are used to dopar the crystals That, very broadly, they are responsible for amplifying the light before emitting it with a fixed wavelength. The problem is that if these chemical elements are not available the production of high quality lasers is not viable. Well, it really wasn’t until now.

And it is that the Fraunhofer Institute of Optronics, which is located in Karlsruhe (Germany), has found a way to manufacture the crystals involved in the production of lasers without using rare earths. In fact, we can see some of these crystals in the cover photography of this article. During its manufacturing process it is essential to minimize impurities and preserve the polarization properties of the crystals, but, apparently, the researchers of the Fraunhofer Institute have given in the Diana. Your plan now goes through developing production processes that guarantee the supply of these crystals that Europe requires.
