Combining 405 single mode & 445 multi mode using pbs cube

[LKY2009]

Hi guys. I was contemplating building a laser by combining a 405 nm single mode beam using a pbs cube with a 445/450 nm multi mode beam. I don't see why this would'nt work, but wanted to get other opinions. The goal would be to get the nice bright beam and high power short range burning ability of the 445 combined with the long distance burn ability of the 405. I figure that by centering the round tight dot of the violet beam near the middle of the blue dash(dot) the resulting burn effect would be very intense. I was hoping to use this PBS cube I found as it is rated for 405 and figure that there would be some loss on the 445 but hoping not too much. Any thoughts?

If you're up to a big project like that, it would be more useful to use some kind of beam correcting optics after combining 2x 445 lasers.

Also if you want the illusion of a "single" laser, you will need to match the divergences, otherwise the lasers will split with distance.

Makes more sense to FAC the 445, or use a prism pair.

So it is doable right?

If you line them up you can make a nice beam it will have a + look with you glasses on.This is a video of one I made 6w 445nm dual diodes night shot most powerful handheld 445 in the world right now - YouTube I am working on new setup will try to up load as soon as I can.

Nice Rick. But with one singlemode and one multimode, wouldn't the round 405 dot just sit in the middle of the 445 dash(dot)? Would I need a 1/2 waveplate with this setup? I figured no since there is only one multimode in use.

just made 2 video of new module 2 diodes module 002 - YouTube
2 diodes module night shot - YouTube I hope the video will help

Hey Rick,

Do you have these available yet?

Hey Rick,

Do you have these available yet?

yes
I am working on putting them on host.
