Luxinar demonstrates how CO2 lasers deliver consistent quality

A conventional CO2 laser operating around 9.3um can branch hop from 9.35um to 9.15um.  This phenomenon is directly linked to the cavity design.

Material absorption varies with wavelength therefore branch hopping leads to variable absorption. Branch hopping is undesirable because it can cause inconsistency when processing materials, particularly in applications such as electronics where process repeatability is critical. Suppressing branch hopping delivers consistent quality and increases throughput by reducing defects and associated costs.

Luxinar develops ingenious solutions for customers and they seek to continuously improve their products and processes, according to their Ingenuity Amplified principle. Luxinar identified that wavelength stability is critical in many applications, and re-engineered their range of CO2 lasers in order to reduce branch hopping, improving the performance of their lasers and delivering tangible benefits to customers. This was achieved without significant impact on the complexity of their own manufacturing process.

Luxinar’s innovative cavity design delivers wavelength purity without compromising on beam quality; our technology produces a high-quality, circular mode. The near-Gaussian beam profile produces high energy density at the focal point, resulting in higher processing speeds when compared to other CO2 laser designs. 

A round beam shape is important in cutting applications, where kerf width must be tightly controlled and consistent in all directions; this reduces the need for additional beam correction and minimises design costs for the customer.

Luxinar’s versatile laser source portfolio of OEM, SCX and SR series caters for a diverse range of industries, including consumer electronics, automotive manufacturing, fashion, food & beverage, packaging, glass, medical and pharmaceutical. Their industrially proven sealed CO2 laser sources are based on a diffusion-cooled slab principle to produce a high-quality, round and symmetrical beam, and our MULTISCAN laser marking systems offer an inkless method to apply text, graphics and barcodes to a wide range of materials.
