Innovations in Ultrashort-Pulse and RF-Excited CO2 Lasers Expand Materials Processing Applications

Presentation will begin: Monday, January 9, 2023 - 2:25 PM EST
Presented by: Jason Lee, Luxinar

Industrial laser materials processing is constantly evolving. Industries as varied as pharmaceutical, consumer electronics, automotive, aerospace, and textiles, among others, have benefited from new or improved processes enabled by an ever-increasing range of laser technologies. From direct diodes to fiber lasers, from CO2 lasers to ultrashort-pulse lasers, the diversity of technology and operating parameters is vast. In this context, “mature” technologies, such as radio frequency (RF)-excited CO2 lasers, can be misunderstood as obsolete. However, RF-excited CO2 lasers have a unique combination of high power and high beam quality at emission wavelengths required for machining most organic materials.

This combination, coupled with relatively low cost, ensure they continue to be industrially relevant which, in turn, drives associated innovation. Alternatively, technologies such as ultrashort-pulse lasers enable new processing approaches that are beyond the capability of more mature technologies. Lee details and contrasts a range of CO2 laser and ultrashort laser applications and demonstrates how these applications have driven innovation for both technologies.
