PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I know, I want a clearer pic of the back as well.
Wow, those cartridges are expensive. :eek:
Thanks for the manual. I've come across the 337 and 337i online, but no manual. Although its for the VSL-337 it should give me a head start and have many similarities.
Good job for not sharing your c drive. :D
I'm wondering whether it would just be easier to make one myself. :undecided:

Manual for the SP version if you want it: https://loci.wisc.edu/sites/default/files/2017-04/VSL-337ND-S User's Manual.pdf

:)

It's fairly easy to make simple nitrogen lasers at home, won't be nearly as good as a commercial unit but it's entirely doable.

https://www.repairfaq.org/sam/lasercn2.htm

Another interesting site:

Expériences lasers et développement de lasers et dragracing

Lots of N2 lasers and big TE CO2 lasers on there (DIY and Commercial), among others. I think there's an SP 337 on there too.

Thanks a lot Diachi. :) I've watched Swiss Rocketman's videos but never came across his site.
I've been investigating the possibility for making TEA lasers for a while. The only thing that puts me off is HV. The supply I was looking at is a 7.5kV 30mA NST and I was going for the asymmetric capacitor design.

The HV and MDF is insulated by Perspex. ;) It is to help with reducing the noise from these lasers, plus I have access to MDF for laser cutting and routering.

I'm still working on this design as we speak.

I think he posted his site/images on PL and that's how I found it haha, in one of Planters' threads about his massive dye laser. Had been watching his videos for a long time too - good channel.

Looks like you've already got everything planned out, looks good! Maybe you'll need a few revisions, but it's looking good nonetheless. :beer:
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Yes, I like his channel. He experiments with a lot. I believe it was his ruby that first got me interested in his channel. Planters is another one that I find interesting as well.

Thanks, I still have a few revisions to make. Mainly future proofing so I can replace parts when they die out and making things safe. But I'm going to wait and see if I can get a manufacture n2 laser first. :beer:
I'll let you know if I get a response from the seller. :beer:

Yeah, keep us posted! Maybe start an N2 laser thread in the gas lasers section.

I tried to buy one of those SP 337s a few months ago but was outbid. :(
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Nice idea! I'll create the thread when I know more of what approach I will take. I get the feeling it will be the homemade one though.
As for that SP 377, what a shame. I know how hard it is to find a working N2 for a decent price.
Was you hoping to start making dye lasers with it too? My first stop, rhodamine 6g.

Always good to see more gas! :)

Yeah, I'd have played around with dye for sure! :D
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Yes, definitely. Even better when you can make it yourself.

Of course. Who wouldn't. :D I will most likely experiment making my own dyes as well. :p

Be interesting to see your dye results too! :)

I need more funds and a workshop so that I can start experimenting with this sort of thing more.

I don't exactly have funds or a workshop either. I'm borrowing space and trying to keep the cost down big time on the parts. :p

But I agree, any results I have with dye lasers will be interesting. :)
I wonder if I could get 580nm to lase superradiantly? :whistle:

Oh yeah, you're a student too right?


Problem here is that there's very little space available, and getting space for free is next to impossible. The spaces that are available are stupid expensive. If I want a house with a garage here I'm looking at >$500,000. Rent is stupid pricey, as is everything else.

Doesn't hurt to try on the 580nm! ;)

Not sure if this showed up in the search I linked earlier or not:

Not anymore. I have a job offer in a sixth form college that I am already familiar with. Hasn't been confirmed yet though.

Yep, it sure is ridiculous. No matter where you are.

Don't you worry, i'll sure try. :D

As for that head, I did come across that. But I'd probably spend more time and money trying to fix/get it running in the end.

I can only assume that you would need to cool it similar to those Coherent FAP-800's. Good heatsink and TEC.
