500W single mode continuous wave 532nm green laser successfully developed
Recently, Israeli high-power laser supplier Civan Lasers announced that the company has successfully developed a 500W single mode continuous wave (SMCW) 532nm green laser, setting a world record for this type of laser.
This green laser was born under the EUREKA project "CBC-Green" led by Fraunhofer IWS, Siemens, and ThyssenKrupp, which aims to create and implement high-power laser beams for more flexible and effective processing of copper materials.
How to run it? What are the benefits?
This 500W single mode continuous wave 532nm laser utilizes coherent beam combination (CBC) technology, which can combine multiple single mode lasers into a single coherent beam with excellent beam quality.
With the help of Coherent Beam Combination (CBC) technology, Civan Lasers' system can achieve high brightness without the risk of damaging the laser crystal (just like using higher laser power to increase brightness), thereby preserving the spectral characteristics of the beam and ensuring long-lasting and reliable performance over time.
It is precisely this CBC technology that enables lasers to use high-quality, high-power beams to improve material processing efficiency and performance, while providing power modulation functions. Considering that 532nm lasers typically require a stable crystal temperature, this is a significant advancement - this ability may break through the current limitations of copper processing. This limitation is caused by high reflectivity (compared to infrared fiber laser radiation, green light lasers exhibit more absorption in the material). This will help the industry better process copper components, which are key to producing energy storage systems, power electronics, control, and necessary cooling structures.
What is the next step?
Although the development of green light single mode continuous wave lasers is still ongoing, Civan Lasers has mentioned their intention to make further progress, based on a series of different material processing applications.
This includes welding high reflective materials such as copper, semiconductor welding, especially chip to wafer welding, as an alternative to traditional metal bonding processes, and 3D printing of copper material products.
Future development plans include reducing the size of the laser by half, significantly reducing its cost, enhancing its power capability, and introducing dynamic beams into green light lasers - ultimately distinguishing them from market competitors.
After further improvement and upgrading, this laser will be sent to the Fraunhofer Institute of Materials and Beam Technology (IWS) in Germany. There, the research institute will lead the development process of two major industrial giants, Siemens and ThyssenKrupp, and further explore the capabilities and potential applications of lasers, many of which are still unknown fields.
