Fiber Laser what Frequency ranges to buy


I’m looking to buy my first Fiber Laser, :blush:
My problem is what HZ ranges to buy
1 -4000 kHz or 50 -100 kHz :thinking:
I guess the 50-100KHz is the “normal” ranges
But what is the advantage with 1-4000Khz and what more can one do with it?
For the 1-4000Khz cost a bit more and is it worth using the extra money?

Get a MOPA, they usually have the widest frequency range.

I have an M60 JPT M7 MOPA, it has complete frequency range up to 4mHz

I understand frequency controls the pulses/sec. Along with this you get a wider Q-pulse range.



Thanks for the answer. But do you use the hole ranges and what for?

I haven’t used the whole range of values, but have been all over them.

Cleaning passes are usually higher frequency, shorter q-pulse… lower frequency and longer q-pulse to put more heat into the material…

Something like the MOPA has the widest range for these values.

If this isn’t what you are looking for, please clarify.

Thanks for the answer.
Has I understand, I’m not able to make color (on stainless) with a 50 -100 kHz !

To get a good variation of color you really need a mopa type. Some of these colors only arrive with short pulse widths in the 8nS area.

Even hatched or non-hatched give you variations.

Have you watched these?

Good luck



Thanks Mr. Jack is just what I needed.

Get a mopa laser if you can afford it with the highest frequency’s possible. It will allow you to engrave in color on stainless. You will thank me later

Thanks, I have one final question.
A ComMaker (all in one) or Cloudray (2 pieces) :wink:
Both are 60W MOPA

Cloudray all the way. If you can get a jpt Mona they are the best

i purposely purchased a split system… box underneath my table and the actual works on the table…

I have four lenses, suggest you get at least a couple. I bought an F420mm lens with 300x300mm coverage. It included an 80cm column.

Send emails to the potential vendors asking about prices … cloudray gave me a discount code for a couple hundred dollars.

I’ve heard very good reports from OMG and Hoation laser companies…

Good luck


Thanks to everyone for all the good answers and ideas.

I’m have order a ComMarker B4 JPT MOPA 100W


That’s great… I’m sure you will enjoy it…

Curious about the price… I clicked the 100W and it didn’t change the price from the 20W model…

Good luck … leaning curve → buckle up for a steep vertical climb…

Don’t forget the best part… have fun :tada:

If you click all the options the price changes. I missed the rotary selection when I checked it out.

I clicked all the various power models, the prices never changed for me.

What does the 100W model cost?


No rotary and 110V

100W $7110
60W $4622
30W $3199
20W $2577

Thanks… sounds more like it.

My split system from Cloudray was around $7k US, … they coughed up a couple extra lenses, rotary and a bunch of testing materials…


Agree, I got my for 6793.- with some extra stuff
