China Femtosecond Laser Precision Marking Machine - High Efficiency 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.
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
Q1: What makes the femtosecond laser unique compared to other lasers?
Femtosecond lasers feature an extremely short pulse duration (only a few femtoseconds), exceptionally high instantaneous peak power, and the ability to focus on a spatial area smaller than a hair's diameter. This allows them to easily release electrons from atomic bonds and form plasma without thermal damage to surrounding materials.
Q2: What are the primary application fields for this equipment?
It is widely used for micro or invisible QR code marking, stainless steel colorful marking, medical forceps and pacemaker marking, fine marking/cutting of thin films, ceramic drilling, glass ink cleaning, and coating removal.
Q3: Can the equipment be safely used for medical device marking?
Yes, the femtosecond laser is ideal for medical forceps and pacemaker component marking. Its ultra-short pulse duration minimizes thermal impact on surrounding areas, ensuring corrosion-resistant, precise, and biocompatible marks.
Q4: What are the configuration models and power options available?
The equipment is available in three models: FRZ-LMF-5F (5W power), FRZ-LMF-10F (10W power), and FRZ-LMF-20F (20W power) to meet different microfabrication requirements.
Q5: What cooling system and environmental conditions does the machine require?
The system utilizes a water cooling mode. It is recommended to operate the equipment in a constant temperature environment of 20°C to 25°C to ensure optimal stability and performance.
