Description

Picosecond lasers can potentially machine materials that suffer from negative thermal effects during nanosecond laser machining with much higher quality. When discussing materials processing, the term "ultrafast lasers" is thrown around a lot nowadays.
It’s often used to describe picosecond and femtosecond lasers in applications. In picosecond lasers, the laser pulse length is shorter than the time taken for absorbed laser energy to diffuse into the substrate, i.e. typically 5 to 10 ps.
Picosecond laser processing is growing in popularity because of the excellent cosmetic finish that can be obtained due to lower heating and reduced debris-related damage.
And not to mention the enhanced coupling due to nonlinear intensity-dependent absorption, and the relative ease with which the machining result can be achieved.
A micromachining picosecond laser can generate a minimum feature size of a width slightly smaller than one micrometer. But this occurs for thin coatings below a thickness of one micron.
A value regarded common is 10 microns laser cut width for deeper beam penetrations. Picosecond laser micromachining is used for high-quality parts that yield the best results.
Picosecond lasers can enable machining techniques that do not rely on ablation. In the scribing of sapphire wafers for the singulation of LED devices, a picosecond laser can produce results with excellent sidewall profiles.
When correctly optimized, picosecond processing can achieve results that are not available with other techniques. Successful implementation requires an understanding and characterization of material-photon interactions, time-dependent process-rate variations, and sample handling if potential benefits are not to be compromised by conflicting system demands.
For top-quality, cost-effective micromachining, we highly recommend working with industry best equipment vendors like Laserod Technologies.
