Osram's latest research project launches a new generation of laser rods
The main feature of CNC cutting machine CNC cutting machine is that it can be processed according to the drawings. It can replace the previous cumbersome and inefficient manual calculation with computer programming, and can accurately cut out various complicated shapes of plates.

Dr. J?rg Heerlein, Head of Laser Product Marketing at OSRAM Opto Semiconductors, said: "The availability of the latest generation of laser sticks has enabled us to create more powerful components." OSRAM has always been a renowned supplier of laser chips and laser rods. This launch of a laser bar with excellent performance and a fill factor of 50% will benefit all laser diode manufacturers. The fill factor of the laser bar is the ratio between the effective width and the total width. This series of laser rods are mainly used for pumping solid state lasers or direct material processing. Based on the existing laser chips with wavelengths between 910 nm and 980 nm and an output power of 120 watts with an efficiency of 70%, we will continue to introduce wavelengths of 808 nm and 880 nm with a power of 120 watts. A laser bar with a conversion efficiency of 62%.
With a 20% fill factor, we are able to create new and better-performing parts that are the best choice for light-coupled applications. The first laser rods to be launched will have a wavelength range of 910 to 980 nm and a recommended output of 80 watts.
New application platform
By using these new and more powerful laser rods, the output power of the system can be greatly improved without affecting the service life. In addition, systems with the same output power are smaller and more reliable.
Samples of new unencapsulated laser rods have been introduced and standard industrial laser rods with a 50% fill factor are expected to be launched in the summer of 2008. In the same fall, laser rods for fiber-coupled applications are available.
From research and development to practice
The BRILASI research project (High-brightness, high-power laser diode FKZ 13N8601 for industrial applications) was initiated by the German Ministry of Education and Research and executed by the German Society of Engineers (VDI), coordinated by OSRAM Opto Semiconductors. The project team consists of representatives from laser systems, end users, and representatives of research institutions. The project aims to develop efficient and reliable laser diodes for industrial applications. OSRAM has successfully achieved the objectives of this research project, and the new laser rods have been developed with powers of 100 to 170 watts in 20,000-hour constant wave (CW) or long pulse mode (depending on emission wavelength and packaging technology). The key is to optimize the epitaxial structure, especially to minimize power loss. Reducing the series power pack does not increase the loss of light absorption. In addition, the project also improved the laser cavity.
CNC cutting machines have been widely used in: agricultural machinery, machinery manufacturing, boiler manufacturing, pressure vessels, wind turbine manufacturing, power equipment, engineering machinery, transportation equipment, chemical machinery, environmental protection equipment, vehicle manufacturing, shipbuilding, coal mining equipment, tower cranes Heavy, bridge construction, building steel structure, steel formwork, road and bridge machinery...
This model is mainly used for precision cutting of large format sheets. It is an energy-efficient cutting and unloading equipment that can greatly improve the utilization rate and cutting efficiency of the steel plate. This machine can work continuously without downtime for a long time.
This model is suitable for medium and high-end users with strength.
