642nm 300mW Homemade Module

could be putting them through a fiber or something and losing 50mw?

Two underdriven diodes.
One overdriven diode
One higher spec'd multi-mode diode.

I would put my money on option 2

T I am about to order a 300mW 532nm module and a 100mW 473nm so this scanner should be pretty decent when completed. All analog modulation of course.

Thanks for checking this out, comments and criticism are welcome.

The 300mW green needs to be turned down to about 1/3th of the power to balance. Some green lasers will not modulate that nice at 1/3th of the power and start to get noisy.
so maybe its better to go for a 150-200mW green.

With the 500-600mW blu-ray I'm adding it would only need to be turned down to 2/3-3/4 to balance for white.

I removed thebluray from my system, cause it looks nice at the power meter, but it does not give the results i was searching for.

I only got bigger safety issues.

[MisterWilling]

Can you give details? How much Blu-Ray did you add and what where the powers of the other lasers? Also What kind of situations do you use the projector for? I would hate to go through all the trouble of setting up the blu-ray and to be dissappointed.

[mccarrot]

Bluray will give you almost no extra brightess, but it will make nice white.

But for beamshows you want to have brightness, so in my oppinioin 405nm is not worth the trouble.

Ahh. I have been convinced to leave blu-ray out of my projector. Thanks for the info.
