Join more laser beams for one high power beam

[Xenom]

My mad mind thought an idea... if i have a lot of 16x red laser diodes can i form a huge laser beam using beam splitters/mirrors?
It is possible?

 

[lemonwonder]

You COULD achieve this yes. It would require painful amounts of precision though.. ugh, i'd give up in 5 mins

 

[sportcoupe]

Yes, search for PBC cube or beam combiner.

Yes, search for PBC cube or beam combiner.

can it be done with optics of dvd burners laser pickup?
beam splitter, mirrors, half mirrors...

Yes, search for PBC cube or beam combiner.

Wow.. I thought it'd just be a bit of tricky mirroring.. Beam combiners look expensive though..

yes, and i dont' want spend a lot of bucks
if it can be done with optics of a dvd burner ok, else i leave the project... :\

i've tried to use beam splitter of a dvd burner as a beam combiner with 200 mW red and 100 mW BR but the BSC splits the beams into 2 beams...

How to fix this?



sorry again for bad english lol

Seems to me the beam splitter is doing it's job - splitting. I think the only way to combine beams is with a, are you ready for this? A beam combiner. :thinking:

Then again, I am not the smartest one here and there may be a way.....

A beam splitter is the same thing as a combiner. I'll draw someting out for you

Check This page out....He combines 4 lasers with 1 pbs cube and some mirrors.

indeed. But my beam splitter also split the combined beam as the image i posted...

thanks!

edit: damn i need to register to look at the photos attached...
can you relink here?

 

[robjdixon]

Not sure if it works with different wavelengths

check out this blu-ray version! This guy did things a little differently, but it came out niceee!

Thanks guys!

OMG the photos of blue rays are awesome!

While this is a nice setup, the main difference between this and the red setup a couple posts back is that the red setup puts out only one beam, whereas the blu-ray setup emits several beams in parallel. Peresonally, I prefer a combining setup that emits one TEM00 (or close to it) beam.

How about a shearing interferometer?

Have multiple beams fill in each other's fringe patterns.

Edit:

Never mind, the angle will be insanely oblique, the beams will mutually interfere, and it's probably just going to be a waste of time without having good alignment tools, which moves it out of the realm of household items and DVD player contents.
