50W JPT LP Series MOPA Fiber Laser for High-Speed Metal Marking
Why High-Volume Marking Shops Pick LP Over MOPA
The 50W LP series gives you serious 50W marking output at a meaningfully lower price than the equivalent M7 or EM7 MOPA machine, putting real ROI on the table for any shop where the work is high-volume standard marking on metals rather than color marking. The 1 to 600 kHz frequency range is six to ten times wider than entry-level Q-switched fiber lasers, which translates directly into smoother surface finishes and cleaner production marks at high speeds. And because the JPT laser source is rated for over 100,000 operating hours and runs entirely on air cooling, this machine has the kind of long-term reliability and operational simplicity that lets you forget it exists and just focus on running production jobs.
This is the right machine for shops doing high-volume standard marking on metals where color capability is not part of the work. Industrial part marking, serial numbers, barcodes, QR codes, logos, dog tags, keychains, brass tags, identification plates, and any production application where the goal is fast, clean, durable marks rather than color or vibrant rainbow effects.
The system is built around the JPT LP series source (YDFLP-E-50-LP-L-R), a real MOPA architecture from JPT but with a fixed pulse width that makes it more affordable than the adjustable-pulse M7 series. You get the JPT brand quality, the over 100,000 hour rated lifespan, EZCad 2 software, full LightBurn compatibility, and the same accessories as our higher-priced machines, all in an air-cooled package that fits any small workshop.
What LP Series Cannot Do
We sell the LP series alongside the M7 and EM7 MOPA machines because each serves a different buyer. The LP saves you money but gives up specific capabilities. Before you order, make sure none of these missing features are important for your work.
No vibrant color marking on stainless steel. Color marking on stainless requires adjustable pulse width control to fine-tune surface oxidation. The LP series has a fixed 200 ns pulse width, which means you cannot produce the rainbow effects, gradient logos, or full color spectrum images that the M7 and EM7 MOPA machines can. You can still do basic light-and-dark contrast marking, but not real color work.
No high-contrast true black on anodized aluminum. True black annealing on anodized aluminum surfaces requires the longer adjustable pulse widths available on M7 series sources. The fixed 200 ns pulse on the LP series produces marks on anodized aluminum but not the deep solid black that MOPA machines achieve.
No optimal heat-sensitive plastic marking. Cool short-pulse marking on heat-sensitive plastics like delicate ABS housings or some thin-film electronics requires the shorter pulse widths available only on adjustable MOPA sources. The LP series can mark common plastics but not as cleanly on the most heat-sensitive materials.
If any of the above are part of your work, choose a MOPA machine instead. Look at our 30W EM7 MOPA for entry-level color marking or our 60W EM7 best seller for full MOPA at mid-range power. Both cost more than the 50W LP but they give you capabilities the LP cannot.
If your work is high-volume standard metal marking (the most common fiber laser application worldwide), the 50W LP saves you real money without giving up anything you actually use.
Five Reasons to Choose the LP Series
Real MOPA Architecture at LP Price
The JPT LP series uses the same Master Oscillator Power Amplifier (MOPA) architecture as the M7 and EM7 series, just with a fixed pulse width instead of adjustable. This is not a basic Q-switched laser rebranded as MOPA. You get the wider frequency range, faster repetition rates, and more consistent pulse-to-pulse stability that MOPA architecture provides, which produces noticeably cleaner production marks than entry-level Q-switched alternatives.
1 to 600 kHz Frequency Range Beats Q-Switched
Standard Q-switched fiber lasers typically operate in a narrow 20 to 80 kHz frequency range. The LP series runs from 1 kHz all the way up to 600 kHz, six to ten times wider. This gives you smoother surface finishes when running fast marking, better mark quality on plastics that respond to higher frequencies, and the ability to fine-tune speed-versus-finish trade-offs that lower-end machines cannot match.
1.25 mJ Maximum Pulse Energy for Real Production Work
The LP series delivers 1.25 millijoules of maximum pulse energy, plenty for high-speed surface marking, deep marking on most metals, and thin metal cutting on thinner materials. Combined with 50W average output, this is enough power for daily production volume on standard marking jobs without wasting capacity on features you do not use.
Air Cooled for Simple Workshop Setup
At 50W with the LP series source efficiency, the machine runs entirely on air cooling. No water chiller, no plumbing, no coolant maintenance, no extra electrical demands. The complete machine fits on a workbench in any small commercial space, garage workshop, or production line. Total power consumption stays under 220W including the source, which any standard outlet handles easily.
JPT Source Quality Even at LP Price
This is a genuine JPT source, not a generic component rebranded as JPT. JPT is the leading fiber laser source manufacturer in China and the same brand used in production equipment worldwide. The 50W LP source is rated for over 100,000 operating hours of normal use. Pulse-to-pulse stability is rated at less than 5 percent variation, ensuring consistent mark quality across thousands of identical parts.

Frequently Asked Questions
This is the official JPT model code. YDFLP stands for Ytterbium Doped Fiber Laser Pulse. The E indicates the economy series internal grade. The 50 is average output power in watts. LP indicates the LP series (fixed pulse width MOPA, lower cost than M7). The L indicates a low-mode optical fiber configuration. The R indicates a built-in red guide laser. Knowing the exact source code matters for warranty claims and parts ordering.
The LP series uses fixed pulse width hardware instead of the more complex adjustable pulse width hardware found in M7 series sources. Adjustable pulse width is what enables true color marking on stainless steel and titanium, true black anneal on anodized aluminum, and optimal cool marking on heat-sensitive plastics. By making the pulse width fixed at 200 nanoseconds, JPT reduces manufacturing complexity and cost. If your work does not need adjustable pulse width, the LP series gives you JPT brand quality at a lower price point.
Limited contrast variations only, not full color spectrum. With the fixed 200 ns pulse, you can produce darker and lighter marks but not the rainbow color effects, vibrant gradient logos, or specific colored details that an adjustable MOPA source produces. If color marking is important to your business, choose the 30W EM7, 60W EM7, or 100W M7 instead.
Higher frequencies allow faster marking speeds with smoother surface finishes. Lower frequencies allow more energy per spot for deeper marking. The full 1 to 600 kHz range gives you flexibility to optimize each material differently. Standard Q-switched fiber lasers typically have only 20 to 80 kHz range, which limits how you can balance speed against finish quality. The LP series wide frequency range is one of the main reasons it produces noticeably better marks than entry-level Q-switched alternatives.
Yes. The JCZ control board is recognized by LightBurn galvo mode on Windows, macOS, and Linux. You will need to set the device profile to use the full 1 to 600 kHz frequency range, because some LightBurn templates default to lower maximum frequencies that assume standard Q-switched sources. Once configured, LightBurn drives the LP series at its full capability.
Very limited. The LP series can cut very thin foils on materials like brass, aluminum, and copper, but it is not the right tool for production sheet cutting work. If cutting is part of your production needs, look at our higher-power machines starting at 100W, or for actual sheet metal cutting consider our CNC fiber laser cutters from 1500W to 6000W.
Yes. The LP series 50W source dissipates less than 220 watts of total power consumption, which the aluminum housing and surrounding airflow handle without issue. Water cooling becomes mandatory at higher power levels (above 100W typically) where thermal load exceeds what air convection can handle.
Different trade-offs. The 50W LP gives you 50W of standard marking power but no color marking. The 30W EM7 gives you only 30W of power but full MOPA color marking capability. If your work is high-volume standard marking on metals, the 50W LP is more productive. If your work involves color marking on jewelry, gifts, or custom items, the 30W EM7 has the right capability even at lower power.
