I just got my 100watt laser tube it's 80mm dia and only 1350mm long is that possable? I see most 100watt's are 1800mm long.

[fly007001]

it would be 1800mm long

[cncadmin]

OOOK well this one is 1350mm and they guarantee it's 100watts max 110watts. They also told me it's a 8000 working hrs.

[zax15uk]

The 100W - 80mm diameter high volume CO2 tubes are usually 1600mm in length, they have additional cooling requirements and are easy to identify. These typically measure 115-120W output and rated at 8000hrs life.

Regular 100W - 60mm diameter tubes are 1800mm as already stated.

I haven't seen a 1350mm length tube rated at 100W, if it's a standard 'cheap' sealed gas, glass tube then I would be suspicious of that rating. The fact that they are also claiming 8000hrs makes me think it could be a newer design, do you have any pictures?

[cncadmin]

It's a serviceable tube also

[zax15uk]

Very nice!

I have seen a similar design, probably the predecessor to this one. It was in a machine made in India.

Zax.

If its not indiscretion, could you tell us about the cost and the manufacturer?
Also, have you run a power measurement? How about divergence?
Thanks.

I had proposal about this NEW type of glass tube from www.kimslaser.com
Really I didn't trust to this information, working time looks like 20-40% more

[Groover]

Any more info on these tubes would be a great help. I would love to be able to get more power in the machine I'm building but the size of tubes is a big restriction. I just cant get a 1800mm tube in the space I have available.

[Litografa]

Hello, Groover
best way ask your local Chinese laser's resellers. At least you'll be sure that tube is working and do not broken.

Paul, you have a nice tube and it is in fact a 100W tube and quite capable of the 8000 hours.

I have a very similar tube manufactured by Laser Engineering here in the states. Its a model M55 , 55" (1390mm) discharge length and is capable of around 120w (100w rated) continuous and over 150w peak in superpulse mode. http://www.laserengineering.com/specs.htm

The tube you have is manufactured differently than typical cheap sealed tubes, and it really is a nice tube.

If you look closely you will see NO adhesives were used in the manufacture of your tube. This is a MAJOR factor.

A major factor in these type of tubes are the metal to glass seals at the optic/electrode mounts. Typical sealed tubes use an epoxy adhesive to glue the optics on. Firstly, this and nearly all adhesives are porous. This allows a constant flow of outside air into the tube, albeit a tiny amount, but it contributes to degradation of the lasing gas. Secondly, these adhesives also gas out their own contaminates into the lasing gas, instantly degrading the lasing gas from the time of manufacture. This is why the cheap tubes dont have the life span of a nice glass to metal sealed tube.

Also, not only is your tube serviceable, its optics are adjustable allowing a perfect alignment of the optical cavity, which is not easily attainable with glued on optics, hence why cheap tubes are typically longer, to make up for this "tolerance" with glued on optics. Which also leads to unwanted modes of operation.

If you look at GOOD sealed tubes made like this, most in the 100W range are around 1400mm long.

My LE M55 is 12 years old, NEVER been re-filled, and is still at least 90% of new. Not sure how many hours is on it, its not 8000, but at least 3-4K.

I also have a Coherent 85w flowing gas system but too $$ to operate.??
how much?
I have seen pics of home built and i would love to build my own. has anyone done this here?

Well, its too expensive for me to operate due to the rental of the cylinder and regulator everytime and refills, for some it may not be too bad. It varies on the cost depending on retailer and location so im not sure in your region but it cost me $150 last time. If you bought a cylinder and regulator that cost would only be a one timer.

I would be willing to get rid of the Coherent really cheap if your interested, or trade for a NEMA 34 600+ oz stepper and driver which I am in dire need of.

The Coherent is fully enclosed in a metal housing. No PSU however, just the tube in the housing. Its fully funtional!!

@KTP, I agree with you somewhat on the RF supply repair, however all the HV DC supplies ive had, I could replace nearly every component other than the transformer for literally under $10, mosfets being the most expensive component, but usually at just a few bucks each. When replacing components like that I always use hot air or pre heat the entire board in a toaster over, makes it MUCH easier.

[knutselsmurf]

I am about to buy a similar laser.
I would like to know from CNCAdmin if it is working well.
The tube looks great anyhow.

[vivinar]

hi,all friend.Now have a laser tube is 1350mm for 100w it is true.
Becuase right now our machine used is such laser tube.it can use for around 8000hours.and it's fuction is steady.

[KPBadger]

Hello Vivinar.

a few questions:-

Is this kind of tube now manufactured in china ?

does it use the same power supply as the old tube?

what is the approximate cost?

available as 100Watt only , or 80w, 60 ?



Thanks very much.

KPB

[vivinar]

Dear KPB

yes,we have such laser tube 100w 1.35m.And it is made in china.
and the detail information about this laser tube,i have send to you with private letter.you can have a check.
we also have 80w,60w laser tube.

[Litografa]

Why do not put detailed information about tube here? Here is forum for INFORMATION EXCHANGE not for PM's

[vivinar]

becuase he want to know this information,so i just told he.and if i am want to do sales-purchasing i can directly to write here,let more people know and this way is more better to do my own business.but i think somebody may don't like.
somebody want to search help about machine in this form and somebody want to find the potential customers in this form.It is free.
I am not force somebody to buy our machines and our things,i also offer them more chances to choose.
so Dear that is my thinking.

[skippy]

Paul, can you tell us how much your tube cost you and which company you got it from? Even a pm with an approximate price would do if you don't want it to be public.
thanks
