Large Aspheres Manage High-Power Laser Energy

Facebook X LinkedIn Email
Expanding the laser beam diameter reduces risks to the optical system, but as aspherical lens diameters increase, so do the fabricating and coating challenges.

PIM MESSELINK AND SHAWN SCARFO, EDMUND OPTICS

Laser system output power is constantly increasing. The maximum attainable peak power of laser pulses has increased by a factor of about 1000 every 10 years1. This pace of progress is similar to the rapid advancements in integrated circuits described by Moore’s law. Developments in optical coating, cleaning, and polishing technology enable optical manufacturers to fabricate components that can be used with high-power lasers, but high-power laser applications stretch — and often exceed — the limits of coating technologies. An alternative approach is to expand the laser...Read full article
