My 445 build

[andy_con]

andy, what driver is that on the board? Will it drive 2 445 diodes ?

read the thread and yes to two diodes

sorry missed the line where you said it. thanks so you are combining the 2 diodes to get 2 watts?

Looks pretty nice to me - the elctrical isolation the 445s make them easier to mount directly into a heatsink.

I guess it would be feasible to knife edge even more of these lasers to end up with a somewhat square beam profile at a distance, but it would be hard to get enough power from other colors to match.

Very cool, I always enjoy seeing your multi-diode-super builds. 445nm is one of my favorites at the moment, so this should be extra cool.

Looks like this is going to be a nice build.

I am awaiting arrival of 4 PBS ordered via PL, for my 445 lab build for my 2nd projector. I have always been curious about "knife edging" but have yet to see a simple example and explanation...

people seem to get hung up on knife edging, its the easiest thing in the world to do. and it does exactly what it says on the tin

Hi Andy, can you recommend a good link/resource for those who have not done it before? I am at a loss as to what you even use. I have seen a fair few images here and there (PL included) but I don't get it. A lot of the images and posts assume a certain amount of knowledge on the subject.

Cheers.

is this any help?

Yes! I saw similar on PL and did not realise this was knife edging!

I was thinking that knife edging involved a sharp edge cutting the beam lol.....

Many thanks.

I resized that pic for you Andy, if you want to copy into your post? I know how frustrated you get that the site doesn't do it automatically!

Looking good BTW.

lol cheers morgan and yes the lack of auto resizing does annoy me

Hi Andy, more of knife edging.

As I have a few FS mirrors that Dave provided to me, all I need is a few mounts and away I go right? So I can Knife Edge just 2 x 445nm K@S10 LD's fitted with Azis glass right? Are telescopics also required? If so, where can I obtain them from?
