Max output for a 635 nm laser, while affordable?

Nope, the GB didn't happen, but they are available from a member there for about $200 after FedExing from the EU.

I've inquired about price if I could get together 10 orders. If there's a price break (there would have to be since I paid like $40 in shipping alone I think), then I'll do a GB for these at the end of April once exams and finals are done.

It would be my first GB here, and I think a unique one

Well, sign me up for it. I'll be waiting.

If we got 10 people together, we could get the final per diode price (to my door) down to $165 USD. Then + shipping costs out to each person.

I'm going to see if there are less expensive sources though. However this is already ~1/3 the Thorlabs price. But there may be cheaper ways. This is a month off at least (too busy right now with moving and finals)

I might be in for one too... but only if you could wait with the payment till 20th May.

Probably be sometime around then anyway. It will be mid May at least.

I wonder if it can be pushed further, but nobody has tried on account of cost?

If they are safely getting 200 mW outta these in those small projector heat sinks and running them for hours at a time I'm pretty sure with a short duty cycle and large heat sink you could squeeze a little more out.

When you get a final price on these could you please drop me a line incase I miss your post.

Cheers

Make a thread in the GB section, no one would except an offer here. So, according to your calculations, it's gonna be as bright as a 500mW+ of regular red and divergent as regular red? YAAAY! :drool:

EDIT: HOLY COW! According to your little calculator: red laser bright as 445?! :worthy:

Then, why not this one ? (assuming the price is "human", ofcourse )



EDIT: http://cgi.ebay.com/Pioneer-DVR-S20...=230599974331&ps=63&clkid=8173912740414463587

The seller does not sell in Italy, so nothing to do for me, but maybe someone in the US can be interested in it

I'm guessing that one would be $300 and up, at group buy price! Lol. That would be even better though!

Lol, there's no offer here Johny. I'm chatting with Jake about the idea, that's all. I've got to move coasts, and get through a grueling 4 weeks before I'll even be thinking about organizing something like this

So for now, it's just chit chat. However, I know that we could get the price to below $190 at least.

We don't know the power of the diode in that burner, but probably low. Remember, it was made 10 years ago. If there had been a powerful 635 single mode diode 10 years ago, we should have see evidence of it by now.

I would be inclined to do a group buy on these, but I wouldn't want to step on rhd's toes or steal his thunder. I have already talked to the guy he would be getting these from about ordering myself one. Would be nice to get it cheaper, but sooner sounds just as good too.

That one is multimode, we all heard terrible stories about the Mitsubishi .5W line generators. The HL63133DG is single mode, that's what makes it so interesting.

Anyway, since 635nm is shorter wavelength than usual DVD lasers, doesn't that mean the DVR S201 would be able to write more data on a single DVD? If not, is the 635nm laser used for authoring? If so, what if all authoring drives have tem?

rhd: What about a feeler then? At least you will know how many people would want them.

This is a reply from Mitsubishi when I was working on the ML520G55 diode a few weeks ago:

Some customers told me that if you need a diverged slow application, such as a laser marker in construction, a multi mode laser is better even they have a large divergence angles at the beginning.

Our single mode laser is main used on laser pico projection.

The single mode laser has a better round shape than mutil mode due to MEMS mirror has a round outline.

In that case, the collimated lens is easy to design and MP

BTW, is anyone of you guys able to get (ask for) a price quote on the ML520G55 from ALIBABA? You must be able to read/write Chinese (or use a translator for reading).

DJNY: The ML520G55 is really low power though - 20mw

Johny: Don't have time to organize and track even a feeler

JakeGT: If you're interested in running a GB - do it No toes being stepped on at all. I'm tied up for the next month at least, so I can't. The same source we both bought from was only 10 Euro cheaper in a QTY of 10. I also found a US source for $175 USD with QTY 1 - though the break there is only at WTY of 500x, and it only goes down to $160.

That doesn't mean anything - other than that it's probably not a steep bulk buy discount regardless of where we get it from. However, it would be worth trying to source them directly from manufacturer perhaps?

Everyone: I'm pretty certain that this (HL63133DG) is the highest power single-mode 5.6mm 635nm diode is the highest power 635nm available right now. Short of going C-Mount (which I wish I had had the time to follow through with ), there isn't a better commercially available diode right now.

There are some other diodes I would love - Like the:
-NDS4113 (488nm, 60mW)
-NDHA210APAE (473nm, 20mW)

But those are thousands of dollars.

WHAT? 488nm diode?! Someone needs to invent a mass produced product that uses them... :bowdown:

This inspired me to do this:
