Someone please explain what this is, it looks really cool, Do the combined colors really make a yellow looking beam? And is it worth it? Thank you :)

Mixed feedback about XPL. You could get lucky and never have to deal with Peng. Or you could get a piece of garbage.
 
Very interesting, it does look yellow but you can also see the red is wider than the green so there is still red visible... very cheap too for a yellow laser though, it is very tempting to buy.

It is indeed, even if its not the same as real yellow its still very cool looking, if only the seller was trustworthy...
 
I have two XPL lasers and they are not the best but certainly functional products, and both are overspec. They've worked fine since the day I got them (in May 2016).

It's called a dichroic mirror. The graph you see on the ebay page shows %Transmittance versus Wavelength. The mirror allows all wavelengths under 565nm to pass through and reflects all wavelengths over 565nm. Basically it can mix red and green to make yellow. Here's a link to a thread I started and a pic of the concept.
