Combining multiple laser beams (same wavelength)

[CDBEAM777]

I must add this thought !!! Not All break thru's come from a lab....somewhere....equipped with million's of $$$ in test equipment.

They are motivated by $$$....where we have a collective passion for all things Laser !!!

It is possible....someone....in our humble group....using the most amazing tool there is....our brain....may....with luck....and ingenuity... make a discovery.

Yes....Lab's are populated by humans in white coats, trained, extremely well funded....all kind's of test equipment, machine shops at their disposal....The deck is indeed stacked !!

But...we have the passion....and our minds !!!

A mere 100 years ago....we would have been the one's making the discoveries !! So...there !!! KEEP thinking....in the box...outside the box...and thru the box !!! Ya just never know !!!!!!!:na::na::na::na:

Interesting discussion. Thought experiment: Perhaps a Brewster's angle setup could be used to combine two polarized beams using only a flat glass optic? One laser's beam would be directed at the glass at Brewster's angle with polarization parallel to the surface; this beam would be almost completely reflected from the surface. From the other side of the glass another laser's beam with polarization perpendicular to the glass is directed at the same place and angle and from the same direction as the first (think mirror image here); this beam is nearly completely refracted through the glass to join the first beam. Sound plausible?
