China Femtosecond Laser Precision Marking Machine - High Efficiency, Fast Speed, Top Suppliers & Factory
Products Description
Femtosecond laser has the following three characteristics: firstly, the duration of femtosecond laser is extremely short, only a few femtoseconds, which is thousands of times shorter than the shortest pulse obtained by electronic methods, and is the shortest pulse that humans can obtain under experimental conditions. Secondly, femtosecond lasers have extremely high instantaneous power, reaching millions of gigawatts, which is hundreds of times more than the total power generation in the world. Once again, femtosecond lasers can focus into a spatial area smaller than the diameter of a hair, making the intensity of the electromagnetic field several times higher than the force exerted by the atomic nucleus on its surrounding electrons. Due to the extremely high peak power of femtosecond laser, after focusing, its intensity can reach the order of 1022W/cm2. Such intensity far exceeds the Coulomb field of internal atomic interactions, so femtosecond laser pulses can easily release electrons from atomic bonds, form plasma, and easily cause material dissociation.
Microfabrication Application:
In the field of microfabrication, due to its minimal impact on the surrounding material, it can be safely cut, drilled, engraved, and even applied in the photolithography process of integrated circuits.

Frequently Asked Questions (FAQ)
What makes femtosecond lasers unique for microfabrication?
Femtosecond lasers have an extremely short pulse duration (a few femtoseconds) and ultra-high instantaneous power. This allows them to focus on areas smaller than a hair's diameter, releasing electrons from atomic bonds to easily dissociate materials with minimal thermal impact on surrounding areas.
What are the primary applications of the FRZ-LMF series?
Key applications include micro or invisible QR code marking, stainless steel colorful marking, corrosion-resistant medical device marking (pacemakers, medical forceps), thin-film cutting, ceramic drilling, glass surface ink cleaning, and coating removal.
Can the pulse width and repetition frequency be customized?
Yes, both the pulse width (<400fs) and the repetition frequency range (1-1000KHz) can be customized to meet specific processing requirements.
What is the recommended operating environment for this equipment?
The recommended operating environmental temperature is 20°C-25°C. A constant temperature environment is highly suggested to ensure stable performance.
What type of cooling system does the equipment use?
The FRZ-LMF laser equipment utilizes a water cooling mode to maintain optimal operating temperatures during high-precision processing.
