Germany is the fastest growing country in the European laser industry, especially in the world of laser material processing. In 1986, Germany proposed the BMFT funding plan funded by 1987-1992 Laser Research and Laser Technology. During this five-year period, the actual investment was 262 million marks. The funding and funding allocation was: laser and components. 36%, application technology and system integration 48.9%, laser measurement and laser analysis 12.2%, other 2.3%; that is to say about 72% of the funding for laser material processing topics (light source, components, systems and methods). The research institutes (FHG, MPG, GFE) have six research institutes, nine large laser centers, and 30 research groups in university research institutes, with a total of about 900 researchers. The more famous research institutes and centers established during this period include: Fraunhofer Laser Technology Institute, Berlin Solid State Laser Research Institute, Hannover Laser Center, and Stuttgart Beam Application Research Center.
According to the statistics of the German Machinery Manufacturers Association - Laser Materials Processing Alliance in 1994, a total of 1364 units of light source (CO2) and YAG lasers for material processing were produced, with an output value of 165 million marks, an increase of 13% over 1993; laser devices The number of units has increased by 39%. In particular, YAG lasers, which are used in marking and dental applications, have experienced a super-proportional growth rate. Therefore, the lasers used in processing technology in Germany are higher than before. German companies (mainly Rofin-sinar Laser, Trumpf Laser, Haas Solid Laser, Lambda Physik, etc.) account for almost 40% of the world market and are in the leading position. In parallel with this, an order contract for 1,544 lasers was signed, worth 177 million marks. In 1994, the turnover of the laser system also reached the production capacity of 860 systems, with a value of 235 million marks, a growth rate of 51%, and a sales growth rate of 17%. At the same time, 937 system contracts were signed with a value of 249 million marks (a growth rate of 58% and an output growth rate of 18%). These contracts are close to the projected production in 1995.
In laser light source, CO2 accounts for 42%, Nd:YAG accounts for 35%; in laser system, CO2 laser processing system accounts for 56%, YAG laser processing system accounts for 40%, CO2 laser processing system Trumpf company is self-supporting, and Rofin-Sinar The company has partnered with Grisheim Co., Ltd. to form the Lascontur series of laser processing machines. The growth of the export sector shows that German companies have strong competitiveness in the international arena, and the German laser industry is still in the ascendant stage.
After completing the BMFT "Laser Research and Laser Technology" funding program in 1987-1992, in 1993 Germany introduced a new funding program for "Laser 2000".
The strategic objectives are:
1 Create the science and technology foundation of the 21st century laser technology field.
2 Support innovative laser technology to maintain and enhance the international competitiveness of laser production and laser industry applications.
3 Eliminate scientific and technological barriers in laser applications.

Start and end of the funding plan: 1993-1997
Amount of funding: 275 million marks
In order to promote laser processing technology, in addition to the establishment of nine national laser centers, a large number of laser processing stations have been established. At the same time, laser processing lines have been actively established in large, medium and small enterprises, such as: gear laser processing lines of Volkswagen; Mercedes-Benz There are 18 factories in the automobile factory, 8 of which are equipped with laser processing production line; Thyssen Steel's car floor laser welding production line; Siemens has established wire package lead laser spot welding production line, contactor core and armature laser welding production line , integrated circuit laser trimming production line and semiconductor wafer laser texturing and annealing production line. In "Laser 2000", it was specially proposed for 94-95 years, providing 5 million marks (25 projects) per year, and subsidizing 200,000 marks for each project of small and medium-sized factories that have approved laser processing technology projects, which greatly promoted German lasers.
