New Reds on the block!

[daedal]

I wanted to get some feedback as I design the new look and feel of the red shown below... any feedback and comments are most welcome...

Total power out the business end with a crappy mirror = ~475mW

Any interest for a module as such (without the cube setup obviously)?

VERY NICE man!!! How hard are you driving them? got any other colors?

Hey Aaron... Overdriving them? Not really... these ones are for personal use and are over-driven as such. The diode spec for the ones I have is 200mW CW.

Other colors? Of course! Here's a violet picture... just snapped :P

P.S. My camera hates taking decent red beam pics... I have not gotten a good one in ages... I might set up the stand this weekend

[Lasernerd]

how much $ are those?

Have not set up the price on these yet, but PM me and we can work something out... it also depends on the diode and color...

I see you were busy last night. I definatly need to find sometime to ride out there.

Lets plan for this weekend then

I'm sure you'll like them

I like the way the driver heatsinks fit the maxxy 'hosts' like that.
I would like to see the violet in more detail.

Hello!
Sorry, but really 200mW CW Diodes with good beamdata aren´t exists yet.
The highest power are the open-can Mitsubishi diodes with 150mW CW and 400mW pulse.The normal mitsubishi diodes (closed-can) with the window have 130mW CW and 350mW pulse. Yes, there exist´s diodes from 200mW-up of watts, but they have a wide stripe emitter and bad divergences on the aixis.
Greetings,

Phil;

It depends on which wavelength you're talking about. I've seen 650 nm and 660 nm diodes that can run 225 mw for extended periods (1000's of hours) with beam specs like 2mm diamter and 1 mrad divergence. Optics play a part in reaching that goal, but we're not talking anything fancy here.

As an example, Marconi used to sell his famous Maxyz modules on E-bay. Quite a few members (including me) are using them in their projectors. Those modules would make between 200 and 250 mw of 658 nm red. They have outstanding beam quality and they've been available for at least 4 years, if not longer.

I also know of at least two people that have gotten similar results with 635 nm diodes at up to 300 mw of power. Granted, the diodes are much more expensive than the one's in a Maxyz module, and the optical train required to tame the beam has quite a few elements in it, but it *can* be done - for a price. (Best spec I've seen so far has been 4 mm beam w/ 1.1 mrad divergence.)

So yeah, 635 nm is the hard one to tame, but it's still possible if you're willing to spend the money on the optics. As for 650 nm and 660 nm, I'd say it's relatively easy to get a good beam at up to 250 mw.
