Advanced Glass Welding
With Lumos’s innovative GHz burst pulsed femtosecond lasers and femtosecond pulsed lasers, an improvement opportunity is unveiled. The ultra-short pulse durations and high precision of these lasers enable a controlled energy delivery to the welding interface, minimizing thermal stress and material deformation while ensuring a robust bond.
The unique advantage comes with the GHz burst mode of our lasers. Delivering lower energy pulses at a high repetition rate, these lasers significantly reduce the risk of material damage, making them highly suitable for delicate welding tasks. Moreover, the GHz burst femtosecond lasers offer greater parameter flexibility, thanks to the additional burst parameters. This aspect makes fine-tuning the welding process possible, which is crucial for applications demanding exact specifications and strong bonds between dissimilar materials.
The applications are bonding glass to silicon for MEMS devices, joining glass to ceramics in optoelectronic components, or welding glass to metals in aerospace and automotive assemblies..
Benefits of utilizing Lumos’s femtosecond laser technology for glass welding include:
- Exceptional Precision: The capability to precisely control the welding process allows for the creation of strong bonds, even in complex or delicate structures.
- Improved Flexibility: The enhanced parameter flexibility facilitates better optimization of welding parameters, ensuring strong bonds between dissimilar materials.
- Three-Dimensional Welding: Explore the ability to create three-dimensional welds, expanding the design possibilities and functionality across a myriad of applications.
