What should i choose YDFLP-E2-200-M7-M-R or YDFLP-E2-200-M7-L-R?

mopa fiber laser 200w

When selecting a pulsed fiber laser source for industrial marking, engraving, or material processing, the choice of model can have a significant impact on performance and final results. Two closely related options in the JPT M7 MOPA family are the YDFLP-E2-200-M7-M-R and YDFLP-E2-200-M7-L-R. While they share many core specifications, the differences in fiber mode type and related beam quality are key to deciding which is right for your application.

So the first import things is you need to clear which kind of job you want to process use the laser machine.

 L version is much better at deep engravings probably due to the higher pulse energy of 2 mJ vs the 1.5 mJ of the M version. 
M version means mopa, it can color engraving on stainless steel and aluminum
 

1. Core Similarities
Both models are part of the M7 series of high-power Master Oscillator Power Amplifier (MOPA) pulsed fiber lasers, offering:
 
Nominal average output power: ~200 W
 
Adjustable repetition rate: ~1 – 4000 kHz
 
Pulse width range: ~2 – 500 ns

Air-cooled design
 
1064 nm wavelength
 
Pulse shaping control and high peak power — ideal for high-speed marking and versatile processing beyond conventional Q-switched lasers.
 
These shared features make both models capable of fast, precise marking on metals, plastics, and other industrial materials.
 


2. Key Difference: Fiber Mode Type
The central distinction between the two models lies in the optical fiber attributes, which affects beam quality and how tightly the laser can focus:
 
M variant (…-M-R) — Near-single-mode fiber:
 
Beam quality factor M² < 1.6
 
Typically a longer armored cable (~5 m)

Provides a tighter, more focused spot size for finer precision.
 
L variant (…-L-R) — Low-mode fiber:
 
Beam quality factor M² < 1.8
 
Typically a shorter cable (~3 m)
 
Slightly larger effective spot and marginally reduced focus sharpness.
 

When to Choose Each Model
➡ YDFLP-E2-200-M7-M-R
 
✔ Best choice if your priorities include:
 
High precision marking and fine detail work
 
Small characters or graphics
 
Deep engraving with minimal heat spread
 
Maximum beam focus quality
 
This model’s better beam quality is particularly helpful when working on detailed designs, tiny text, or when you need sharp, high-contrast marks.
 
➡ YDFLP-E2-200-M7-L-R
 
✔ Best choice if you want:
 
Slightly more cost-effective option
 
Good performance for general marking and engraving
 
Solid capability on larger marks or less precision-critical applications
 
Because the L-fiber version has a bit looser beam quality, it performs well in everyday industrial marking where ultra-fine beam focus is not the priority.
 
4. Practical Considerations
 
Application frequency:
Both lasers support a broad frequency range and adjustable pulse widths, enabling flexible performance for different materials and marking speeds.
 
Installation:
Check whether your scanning/guiding optics and workholding setup can take advantage of a higher-quality beam. The M version’s tighter focus might require slightly more accurate mechanical alignment.
