Introduction
With the development of high precision fabrication, ultra-fast laser has been widely recognized as the most promising technology for advanced industrial materials processing. The femtosecond laser and the picosecond laser are the two systems that are the most popular as of now.Both picosecond and femtosecond lasers have less thermal damage, better processing precision and better surface quality than conventional nanosecond lasers. These properties make fill layers and drills via-hole, micro-drilling, glass cutting, semiconductor processing, PCB manufacturing, medical device manufacturing and precision laser marking.Now worldwide manufacturers have been eager to reliable solution of picosecond laser and femtosecond laser to increase production efficiency, product quality and automation level.
What Is a Picosecond Laser?
A picosecond laser is a laser system operating with pulse durations within the picosecond domain (1 ps = 10-12 s).Since the material absorbs laser energy before heat can diffuse to the neighbor areas, because the pulse duration is so short.Therefore, a particularly good quality can be obtained with a picosecond laser:
- Minimal heat affected zones
- High precision processing
- Smooth cutting edges
- Reduced material deformation
- Excellent marking quality
Modern picosecond laser systems are widely used in precision industrial manufacturing where accuracy and surface quality are critical.
What Is a Femtosecond Laser?
A femtosecond laser operates with even shorter pulse durations than a picosecond laser. One femtosecond equals 10⁻¹⁵ seconds.
Because of the extremely short pulse width, a femtosecond laser can process materials with almost no thermal effect. This technology is often called “cold laser processing.”
A femtosecond laser is ideal for:
- Semiconductor wafer processing
- Sapphire cutting
- OLED manufacturing
- Medical stent cutting
- Precision micro-machining
- Scientific research
- High-end glass processing
For ultra-fine industrial applications, femtosecond laser systems provide exceptional accuracy and edge quality.
