True green diode laser rgb build

[steve-o]

I would definitely go with s-polarity on this one for the green diode (I'm sure that you've already seen that on the spec sheet).

-edit-..and congratz for being one of the 1st to acquire one of these lil monsters.. I'm sure the best is yet to come ..
I'm greeeeeeeen with envy too :]

Kecked,

ED over at Electrical Eng. has point and shoot measurement with a Ocean Optics fiber spectrometer.
All you have to do is hike up seven flights of stairs. Its not involved in a active experiment.
It has one of the Ebay surplus B&W 472 blues hooked to it, so its worth the trip.

I'd invite you to use my boss's ICCD, but its calibration is "In Progress" for another wavelength band.

What about trying a ca$io dichro; both of them seem to be very angle sensitive.

[planters]

I would stay away from the broad band PBS. At a given quality level ( read dependent on who you order from) the narrow band always work better. And this makes sense.

Of course if...

I wonder if using a full wavelength PBS cube might be a better way to go. I can combine the red and blue using a normal dichro and then use the cube to combine the green with the red and blue.

Then you will be limited to 3 single diode sources.
Are the trails you are talking about due to the slow/delayed modulation of the DPSS? Any application for the Stanwax color correction board here?

Wouldn't that be the DZ CC board.

some of that stock is 98% reflect 96% transmit. That is amazing stuff.[/QUOTE]

We've been getting suckered on Dichros for greater then 20 years in this industry. One Stop and a few of the Asians made tremendous strides in the past two years.

When I started, out of a 150 mW 60X doing split and recombine color, + 25 mW hene, I got ~30 mW of RGB on the screen.
That was why the PCAOM was such a Godsend.

That's why I am real happy to see 200mw of whitelight. I remember those days. Hell when 35 mw red diodes came out it was a big deal. I paid a few hundred for one that then died. Same withthe blues. I paid $400.00 think that was a bargin for 50mw. Few months later the casio stuff arrived and changed everything.

I contacted Bob on ebay. We will see if he replies. Worst case I'll try one stops stuff and see how it looks. I can always change it out.

What I really hope for is clean blanking like I use to have running pcaom. Good beam profile is next followed by Power.

[kecked]

I am having fred at onestoplaser make me a custom run of dichro. Looks like the right ticket. If it works, I'll have some extra dichro if anyone else wants to try this. I'll sell it at cost since I only need one piece and I have to have an entire run done.

Have you looked at the Edmund LONG PASS laser beam combiners, or the more expensive Semrock MUX filters? The performance is extraordinary.

Wouldn't that be the DZ CC board.

That might be. I obtained the color correction board from Stanwax, but the origin may be DZ. I only know of one example.

[swamidog]

yes. dz sold the design to stanwax. i have one of the original dz models in my projector. it makes a profound difference for beams and abstracts, but it does kind of mess up rasters.
