In the field of high-end laser cleaning and precision manufacturing, the controllability of pulse energy and peak power directly determines processing quality and application boundaries. Through continuous technological upgrades, Foster Laser has achieved highly flexible and efficient parameter customization based on MOPA pulsed laser cleanner technology, providing tailored solutions for various industrial applications.
Taking the M7 and M8 series as examples, under the same power range and pulse width conditions, the system enables customizable pulse energy enhancement from 100% to 500%, while peak power can be increased to more than 10 times the original level. This high dynamic adjustment capability significantly improves performance in complex material processing and precision surface cleaning applications.
MOPA Core Technology: Precise Control of Every Laser Pulse
MOPA (Master Oscillator Power-Amplifier) architecture consists of a seed laser source driven by electrical pulses (LD) and a fiber amplifier system, enabling precise control of pulse width, frequency, and energy output.
Foster Laser has developed a mature product portfolio, including:
LP series, M7 series, M8 series, CL series, etc.
Among them:
M7 series is single-mode
CL series: only models ending in “-1” are single-mode, others are multi-mode
The power range covers 20W to 2000W mass-production models, meeting diverse application requirements from precision cleaning to heavy industrial surface treatment.
Versatile Beam Modes for Different Material Applications
In laser processing, beam mode and energy distribution play a critical role in determining processing results. With increased pulse energy flexibility, the beam profile can also be adjusted for more precise energy control.
The system supports multiple spatial energy distribution modes, including:
Gaussian beam (Gaussian distribution)
Flat-top beam (uniform distribution)
Available beam shapes:
Circular spot
Square spot
Where:
Single-mode beam (Gaussian beam) features a cone-shaped energy distribution with high energy concentration, making it ideal for high-precision processing applications.
Multi-mode beam (Flat-top beam) provides a more uniform energy distribution with reduced impact on the substrate, making it more suitable for large-area cleaning and delicate surface treatment.
More Precise, Gentle, and Efficient Cleaning Performance
Through flexible pulse modulation and beam mode switching, Foster Laser systems can seamlessly adapt to different processing scenarios. While maintaining high efficiency, they minimize material damage and achieve a balance between high-performance laser cleaning machine and precision protection.
This highly customizable laser output capability makes the system particularly effective in applications such as metal rust removal, coating stripping, and precision mold cleaning.
Conclusion
With customizable pulse energy, scalable peak power, and multi-mode beam control, Foster Laser is redefining the technical standards of high-end laser cleaning, delivering smarter, more flexible, and more reliable laser processing solutions to global customers.
