Alright, still working on this and wanted to post my progress! I actually made this from scratch in Fusion 360 and after many versions it is coming together. Still needs more work, but the idea is that the lens holders are pretty much a single piece with threads I split in two that has a spot for...

Hmm, thats odd. Well, i sent them a message through email and ebay monday and i have yet to get a reply. We'll see what happens. I got the RF dummy load, waiting for mineral oil to show up to fill it. It's a variant of the old cantenna. -Jerry

That's really cool.

What would you do with a 375nm diode?

LaserBoy can read and write all formats of ilda and ctn files. There is even a ctn.wtf settings file for proper optimization for ctn files.

No they do not have to be heavy or expensive, nor even large. Pics soon coming of an Image Engineering Beam table. Steve

Amazing they can do it for these prices.. But i think cheap tooling costs along with using the tools to the point of breakage is how they do it. I wonder how well the tolerances are (if they matter to you) as i know most cheap machined things are machined fast which messes with any sort of...

Yo! Your Converter helps me a lot but i got issue with colors.... My laser read every animation in format 0, sadly only recognize purple color. I tried everything to find solution..... If you know how to fix it i will be very appreciate. Regards

What ever you do have a written agreement, I've heard of too many Co2's perpetually disappearing during rebuild / shipping., Steve

Damn, I can't even see the image I just posted. I notice a lot of cross origin read blocking warnings in the console of the chrome devtools...

I see this:

can you see these/?------------------------

I can only see the image with the holes. The other two I see the filename with the broken image icon in front.

I am seeing two pics and a size diagram for making holes..what do yo see? hak

I remembered we had an old Coherent Gem-Q600 at work, it's an old 60w q-switched CO2. Yeah, weird... Anyway it is also excited at 100MHz so I measured the length and it came to exactly 4.6 meters just like the chart so I am ordering some more wire and ends and going to give the cable a second...

I have a friend at PSU that has a 1500W load and another buy offered to give me what looks like a military version of the old cantenna that I can have so I think I am good to go. Thanks for offering though! I talked to a guy at work, we integrate much bigger Coherent Diamonds in the PCB machines...

Interesting, I got this 100w tube for a song to I might give a try with evergreen since worst case is I need to start fresh with another surplus tube. The 30w synrad in my laser cutter is down to about 7w after it warms up so I need to figure something to pretty soon Also - macona I have a bird...

I was looking at a laser for a COVID emergency project. . Before I shot my mouth off and recommended a purchase I'd regret, I went down to look at Photovac. Only an hour and a half from here. Like, I said, suitably impressed by the care, quality, and testing. Not to mention the PhD who perfected...

If it’s a match issue try a 2M ham tuner. 600w 100mhz what rms peak to peak? Make sure the tuner can handle the load. Might be easier to roll your own. Can you drive the load through the cable to a dummy load? Put a Bryd watt meter in like and measure the reflected and forward power. If it...

Coherent has stopped supporting these lasers so that means whoever can service them can pretty much charge whatever they want. And do so. I talked to coherent through work last week trying to get a manual for this specific model I have and they don't even have manuals anymore. The guy in CT is...

I had a quote from photovac -- for my 100w they said $500 just for eval, and then typically $6500 for a refurb. It was years ago but I got a quote from Bell Laser for $1500 and there is the guy in Connecticut on ebay who says $1000 for a 100w gem. Have any of you use these vendors? The price...

MUCHO GRABASS Mr Roberts--hak*retardo

Got a working an calibrated OSA underway! It's shown to be working and is delicately shipped as i am aware that OSAs have fragile parts that can easily damage in shipment. 600nm to 1600nm at 0.1nm resolution In the end paid about 620 euros delivered.. So that's well within my budget! The...

Ahh, thanks. I had ran across their site while trying to dig up info on the RF cables. Saw a whole thread there about Bell laser and Evergreen mixed in. Is evergreen no good anymore? I seem to remember them being the go-to guys for getting tubes redone.

Photovac outside Columbus Ohio is the real deal.. Multiple plants, multiple employees. I visited on business. I was suitably impressed. Steve
