50W JPT LP Fiber Laser Engraver for Fast, Deep Contrast Marking on Metal
Why Production Shops Choose the 50W LP
The 50W LP gives you a full 50W of JPT fiber laser power at a lower price than a MOPA machine of the same class. The source is the JPT YDFLP-E-50-LP-L, a non-MOPA pulsed fiber laser with a fixed 200 ns pulse and up to 1.25 mJ of pulse energy. That combination is built for one thing: fast, clean, high contrast marks on metal, part after part, all day long.
This is the machine for industrial part marking, serial numbers, barcodes, QR and Data Matrix codes, logos, dog tags, brass tags and identification plates, plus deeper engraving on stainless steel, aluminum and brass. If color marking is not part of your work, you get more marking power per dollar than with any MOPA source.
Around the source you get the same hardware package as our MOPA machines: a Sino-Galvo SG7110 scan head with 10 mm aperture and up to 5000 mm/s marking speed, an original JCZ controller with EZCad 2, full LightBurn compatibility and the same accessories. Everything is air cooled and runs from a normal wall outlet.

What the 50W LP Cannot Do
We sell the LP next to our M7 and EM7 MOPA machines because each one fits a different buyer. Check these limits before you order.
Capabilities the 50W LP Does Not Have
No color marking on stainless steel or titanium. Color marking needs an adjustable pulse width to control the oxide layer. The LP is a non-MOPA source with a fixed 200 ns pulse, so it produces dark and light contrast marks, not rainbow colors or color gradients.
No deep jet black on anodized aluminum. The 50W LP removes anodizing cleanly for bright white marks. The deep solid black that MOPA machines create needs very short adjustable pulses, which the LP does not have.
Not the best choice for heat sensitive plastics. Cool marking on delicate plastics also depends on short adjustable pulses. The LP marks many common plastics, but a MOPA or UV laser gives cleaner results on the most sensitive ones.
If any of these matter to you, choose a MOPA machine. Look at our 30W EM7 MOPA for entry level color marking or the 60W EM7 best seller for full MOPA at mid range power.
If your work is standard metal marking, the most common fiber laser job in the world, the 50W LP saves you money without giving up anything you actually use.
Built for Production Volume
Five Reasons to Choose the 50W LP
1
Full 50W at a Lower Price Than MOPA
The JPT LP series is a non-MOPA pulsed fiber laser with a fixed 200 ns pulse. Dropping the adjustable pulse hardware is what makes it cheaper than an M7 or EM7 MOPA source. You pay for marking power, not for color features you will never use.
2
Full Power From 40 to 600 kHz
The source runs from 1 to 600 kHz and delivers its full 50W anywhere from 40 kHz up to 600 kHz. High frequencies give smooth, fast fills for logos and codes. Lower frequencies put more energy into each pulse for deeper, harder hitting passes.
3
1.25 mJ Pulse Energy for Deeper Marks
Each pulse carries up to 1.25 millijoules, a big step up from the 0.8 mJ of the 20W and 30W LP sources. That extra energy removes metal faster for deep engraving on stainless steel, aluminum and brass, and it keeps production marks crisp at high speed.
4
Air Cooled, Simple to Install
No water chiller and no plumbing. The JPT source is air cooled with smart fans and draws less than 220W from its 24V DC supply. The complete machine runs on standard single phase power from 110 to 240 V and fits on a normal workbench.
5

Full Power Frequency Explained
JPT lists 40 kHz as the power reduction frequency for the YDFLP-E-50-LP-L. From 40 to 600 kHz the source delivers its rated 50W. Below 40 kHz it holds its 1.25 mJ pulse energy and the average power drops. Keep this in mind when you build your own settings in EZCad or LightBurn.
Cost vs Capability
50W LP vs 60W EM7 MOPA
The most common comparison buyers make is the 50W LP against the 60W EM7 MOPA. The decision comes down to one question: do you need color marking?
| Feature | 50W LP (This Machine) | 60W EM7 MOPA |
|---|---|---|
| Source type | Non-MOPA, fixed pulse | MOPA, adjustable pulse |
| Pulse width | Fixed 200 ns | 2 to 500 ns adjustable |
| Frequency range | 1 to 600 kHz | 1 to 4,000 kHz |
| Max pulse energy | 1.25 mJ | 1.5 mJ |
| Color marking on stainless | No | Full color range |
| Black marking on anodized aluminum | Limited | Deep black |
| Standard metal marking | Excellent | Excellent |
| Cooling | Air cooled | Air cooled |
| Best for | High volume standard marking, no color needed | All around shop with color capability |
| Price position | Lower | Higher |
Choose the 50W LP if you do production marking on metals and color is not part of your business. Choose the 60W EM7 MOPA if you offer or plan to offer color marking, need deep black on anodized aluminum, or want maximum flexibility for future jobs.
What Buyers Ask
Practical Concerns Before You Order
Setup and Day One
Assemble, focus, mark. The laser source is installed and tested before shipping. Mount the Z axis, connect power, install EZCad 2 from the included USB drive, focus with the red dot and run your first job. Air cooling means no chiller to fill.
LightBurn Frequency Settings
Set the frequency range to 1 to 600 kHz in the device profile. For full 50W output, run your jobs between 40 and 600 kHz. Pulse width is fixed at 200 ns, so there is nothing else to set for the pulse.
Customs and Shipping Costs
The price you see is the total cost. Free DDP shipping to the US, Canada and EU includes all customs duties, import taxes and brokerage fees. No surprise invoices from a customs broker.
Will I Regret Not Buying MOPA?
Only if you need color marking. For metal marking, serial numbers, barcodes, QR codes, dog tags and identification plates, the LP handles all of it. If you may offer color marking later, a MOPA machine is the safer choice.
Power Requirements
Standard single phase power. The JPT source itself draws less than 220W, and the complete machine runs from any 110 to 240 V single phase outlet. No three phase service needed.
Service Coverage
2 years of full coverage with shipping included. Failed non-source parts ship to you free with no return required. Source defects are repaired or replaced through JPT warranty with all freight covered.

Detailed Questions
50W JPT LP Questions and Answers
What does YDFLP-E-50-LP-L-R mean?
It is the official JPT model code. YDFLP stands for Ytterbium Doped Fiber Laser Pulse. E is the JPT E type control. 50 is the average output power in watts. LP means the LP series with a fixed pulse width. L means low mode fiber with M² less than 1.8. R stands for the built in red pilot laser. Knowing the exact code helps with warranty claims and parts.
Is the 50W LP a MOPA laser?
No. The JPT LP series is a non-MOPA pulsed fiber laser with a fixed 200 ns pulse. That is why it cannot do color marking, and also why it costs less than an M7 or EM7 MOPA machine with the same power.
Why is the LP series cheaper than M7 MOPA?
MOPA sources have extra hardware to adjust the pulse width, which enables color marking, deep black on anodized aluminum and cool marking on sensitive plastics. The LP keeps the pulse fixed at 200 ns, so it is simpler and cheaper to build. If you do not need those features, the LP gives you more power for the money.
Can the 50W LP do color marking on stainless steel?
No. With the fixed 200 ns pulse you get darker and lighter contrast marks, not colors. If color marking is important to your business, choose the 30W EM7, 60W EM7 or 100W M7 instead.
Which frequency should I use?
Use 40 to 600 kHz when you want the full 50W, which covers most production marking. Higher frequencies give smoother fills at high speed. Go below 40 kHz only when you want fewer, harder pulses, because average power drops there while pulse energy stays at 1.25 mJ.
Does the 50W LP work with LightBurn?
Yes. The JCZ controller works with LightBurn in galvo mode on Windows, macOS and Linux. Set the frequency limits in your device profile to 1 to 600 kHz so LightBurn can use the full range of the source. The LightBurn license is purchased from LightBurn.
Can the 50W LP cut metal?
Only very thin foil. For regular cutting of thin metal sheet, look at our 100W and higher M7 machines, or our CNC fiber laser cutters for real sheet metal production.
Is air cooling enough for 50W?
Yes. The JPT LP source is designed for air cooling. It uses smart fans that run at full speed for 3 seconds at power on, then follow the source temperature and stop below 27 °C. Keep the room between 0 and 40 °C and leave free airflow around the source. Used this way, the fiber source is built for up to 100,000 working hours.
Should I buy the 50W LP or the 30W EM7 MOPA?
The 50W LP gives you more power for fast standard marking and deeper engraving, but no color. The 30W EM7 gives you less power with full MOPA color marking. Pick the 50W LP for high volume metal marking, and the 30W EM7 for color work on jewelry, gifts and custom items.
Where can I download the datasheet?
Use the Download datasheet button next to the SKU at the top of this page. It opens the official JPT LP series manual with all optical, electrical and environmental data for the 50W source.
