Fluence Femtosecond Lasers Provide Cutting-Edge Performance

Here at Fluence, we love it when robustness meets performance – especially in the topic of femtosecond lasers.

With that in mind, we’re excited to confirm we have reached a state-of-the-art ablation efficiency of 16 mm3/min (0.8mm3/Wmin). This was obtained with the Fluence Jasper femtosecond laser for a soda lime glass substrate, resulting in the finest edge and surface quality, and no damage to the surrounding material.

We don’t stop there. With our THG module, you’ll be able to reach ablation rates 10 times higher than this, for materials like heat sensitive plastics. So useful for the OLED displays manufacturing.

Why use a femtosecond laser?

Femtosecond lasers bring new possibilities to industry and science that were impossible to obtain with traditional methods. One of these possibilities is called cold ablation – a physical phenomenon that helps remove material without excessively heating the surrounding sample.

But is this process fast enough to meet the industry expectations?

Each pulse from a femtosecond laser carries enough energy to remove just a miniscule amount of the material. However, Fluence’s Jasper laser can provide over 1 million pulses per second, adding up to a volume that has a substantial effect. What’s more, Jasper parameters like repetition rate, pulse energy, average power and pulse duration can be precisely adjusted – making cold ablation a highly controllable process.

It’s no surprise that femtosecond lasers have found their way into micromachining applications, where high process precision and quality are always welcome additions. Cold ablation achieved through the use of a femtosecond laser keeps thermal effects at a minimum. As a result, it’s possible to avoid micro-cracks and material weakening, whilst femtosecond lasers also allow you to work with very sensitive materials – like biopolymers and LCD displays.

Femtosecond lasers are also hugely advantageous when it comes to processing materials that were always considered to be ‘unmachinable.’ The peak power of a single pulse can soar to hundreds of megawatts, leading to ablation in even the most difficult of materials – like tempered glass, titanium, sapphire and diamond.

Reach 60 W of ablation with the Fluence Jasper

Does cold ablation sound like a useful process for your business? Now available in a 60W version, Fluence’s Jasper series is a powerful and reliable femtosecond laser source that will simply make it work. Here at Fluence, we hope you choose us for all applications of femtosecond laser technology!
