Femtosecond Fiber Laser for Reliable Material Processing

Fluence, a femtosecond fiber laser manufacturer for material processing and other applications, offers the Jasper 100 laser, a custom version of the Jasper X0 series fiber laser.

In lab testing with the Jasper 100 laser, Fluence achieved a 200 fs pulse at 100W average power. "While some competing lasers claim output power of up to 300W, these free-space lasers are costly, include mirrors that suffer from misalignment issues, have longer pulse durations and require more maintenance at lower duty cycles than the Jasper 100 fiber laser," said a company spokesperson. "Jasper femtosecond lasers are built using a unique all-fiber, monolithic and SESAM-free oscillator. Using the fiber construction, the lasers pose no risk for misalignment, providing customers with a dependable, high-performance laser for disparate industrial applications."

The Jasper 100 operates at repetition rate of 20 MHz, delivering 5 mJ of energy per pulse. With a high repetition rate and shorter pulses at this power output, the laser can create repeatable, precise and clean micro features in micromachining applications, according to the company.

"With a 30 µm spot size, the laser provides optimal fluence for stainless steel or aluminum processing at a very high repetition rate," said Bogusz Stepak, Head of Laser Material Processing at Fluence. "Without using beam shaping optics, users can obtain high processing speeds in the range of 300 m/s when combined with a fast polygon scanner, making the laser very attractive to industrial users and production lines."

The Jasper family of ultrafast lasers serves a variety of industrial applications, such as patterning, marking, micro and nanostructure formation for producing superhydrophobic or anti-icing surfaces on various materials, as well as laser milling, glass cutting and display processing.
