🎉🎉🎉To further enhance technical capabilities and laser application services, Foster Laser invited the JPT technical team to conduct a specialized training session. The training provided systematic insights into the core principles, product portfolios, and industrial applications of MOPA pulsed lasers and nanosecond solid-state lasers, comprehensively improving the professional capabilities of both sales and technical teams in product selection, process applications, and industry-specific laser solutions.
Technical Overview of MOPA Pulsed Lasers
MOPA (Master Oscillator Power-Amplifier) pulsed lasers consist of an electrically driven LD seed source combined with a fiber amplifier. These lasers offer adjustable pulse widths, high peak power, and exceptional processing flexibility.
JPT’s current MOPA pulsed laser portfolio includes the LP, M7, M8, and CL series, with mass-production power ranges from 20W to 2000W, meeting diverse industrial processing requirements such as precision marking, deep engraving, cleaning, and cutting.

Key features include:
💎The M7 series adopts single-mode output, delivering excellent beam quality.
💎The CL series, except for CL-1, primarily utilizes multi-mode output, making it more suitable for large-area cleaning and surface treatment applications.
As pulse energy increases, the laser spot mode changes accordingly, enabling optimized processing performance for different materials and applications.
Typical Applications of MOPA Pulsed Lasers
Metal Deep Engraving
High pulse energy enables fast and efficient deep engraving while maintaining finer textures under high-frequency parameters, making it ideal for molds, hardware components, and industrial parts processing.
Acrylic Paint Removal and Coating Processing
Laser technology precisely removes surface paint and coatings with smooth, burr-free edges and excellent transparency while achieving clear pattern marking.
Stainless Steel Color Marking
With independently adjustable pulse width and frequency, MOPA lasers offer extensive parameter combinations, enabling a wide range of high-quality color effects on stainless steel surfaces.
Plastic Bitmap Marking
Suitable for high-precision bitmap marking, logos, and parameter identification on plastics and non-metal materials, delivering sharp images with minimal material damage.
Fish Scale Texture Marking
Widely applied in smartphone middle frame processing and other 3C electronic products, laser fish scale engraving enhances both surface aesthetics and material conductivity.
In addition, high-peak-power lasers demonstrate excellent performance in anodized layer removal, restoring conductivity without causing material deformation. Galvo-based pulsed laser cutting also offers advantages such as lower laser equipment integration thresholds and easier optical integration, particularly suitable for thin metal sheet cutting.
Introduction to Nanosecond Solid-State Lasers
Nanosecond solid-state lasers use solid crystals as the gain medium, providing high stability, high precision, and superior micro-processing capabilities.
🔥Current product lines include:
Seal Series
Lark Series
Sparrow Series
Power ranges cover:
✅0.8W–30W UV laser sources
✅2W–40W green laser sources
These lasers are widely used in high-precision processing industries including semiconductors, PCB manufacturing, glass, ceramics, and polymer materials.
Customizable Energy Density Distribution
JPT lasers support multiple spatial energy distribution modes that can be customized according to different processing requirements, including:
✨Gaussian distribution (single-mode beam)
✨Flat-top distribution (multi-mode beam)
Various beam shapes, such as circular and square spots, are also available.
Among them:
🔔Single-mode Gaussian beams concentrate energy efficiently, making them ideal for precision cutting and fine processing.
🔔Multi-mode flat-top beams provide softer and more uniform energy distribution, effectively reducing substrate damage and making them more suitable for surface cleaning and large-area processing.
Features and Advantages of UV Laser Technology
UV lasers feature short wavelengths, excellent focusing capability, high energy density, and superior processing resolution, making them highly advantageous for ultra-fine precision processing.
Key advantages include:
💎High processing accuracy
💎Excellent beam quality
💎Minimal heat-affected zone
💎Narrower processing linewidths
💎Reduced material damage
UV lasers have been successfully applied to metals, semiconductors, ceramics, glass, and various polymer materials, particularly in high-quality drilling, precision cutting, and grooving applications.
Typical Applications of Nanosecond Solid-State Lasers
Precision PCB Processing
Widely used in medical devices, industrial equipment, automotive electronics, lighting systems, and 3C electronics industries.
QR Code and Character Marking
Enables high-precision QR code and character marking on circuit boards, supporting product traceability and intelligent manufacturing management.
Plastic and Consumer Product Marking
UV laser processing is known as “cold processing,” making it suitable for nearly all plastics and non-metal materials while delivering high-quality marking without burning or deformation.
Stubborn Coating Removal
Leveraging the short wavelength and high peak power density of UV lasers, coatings such as paint layers, adhesive layers, and plating can be efficiently removed while maintaining substrate integrity.
