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:<\/p>\n
- \n
- Minimal heat affected zones<\/li>\n
- High precision processing<\/li>\n
- Smooth cutting edges<\/li>\n
- Reduced material deformation<\/li>\n
- Excellent marking quality<\/li>\n<\/ul>\n
Modern picosecond laser systems are widely used in precision industrial manufacturing where accuracy and surface quality are critical.<\/p>\n
What Is a Femtosecond Laser?<\/p>\n
A femtosecond laser<\/strong> operates with even shorter pulse durations than a picosecond laser. One femtosecond equals 10\u207b¹\u2075 seconds.<\/p>\n
Because of the extremely short pulse width, a femtosecond laser<\/a> can process materials with almost no thermal effect. This technology is often called “cold laser processing.”<\/p>\n
A femtosecond laser is ideal for:<\/p>\n
- \n
- Semiconductor wafer processing<\/li>\n
