Here the article describes how many lasers have been combined into one by means of fiberglass rods. If this works out to be practical perhaps this could be a way to use fifty 0.2watt dvd lasers to form a 10watt sintering laser. Anyways, just an idea.. I just wanted to throw this out there. https://reprap.org/forum/read.php?215,305172,305172#msg-305172 Fri, 11 Sep 2026 15:36:35 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?215,305172,530443#msg-530443 https://reprap.org/forum/read.php?215,305172,530443#msg-530443 TheTechnicalNoob MetalicaRap Wed, 08 Jul 2015 15:28:56 -0400 https://reprap.org/forum/read.php?215,305172,530284#msg-530284 https://reprap.org/forum/read.php?215,305172,530284#msg-530284 printa3d MetalicaRap Wed, 08 Jul 2015 07:48:09 -0400 https://reprap.org/forum/read.php?215,305172,350910#msg-350910 https://reprap.org/forum/read.php?215,305172,350910#msg-350910
Using multiple diodes of the same wavelength won't get you much as a result, since the wavelengths are not controlled, unless you also temperature control them. This is the reason that people usually knife edge the beams to stack them, and combine them that way, alas this type of multimode beam will not focus to a spot at all.

You can find many articles that describe these beam combining problems on the laser forums, like photonlexicon.]]> manton MetalicaRap Tue, 06 May 2014 02:20:48 -0400 https://reprap.org/forum/read.php?215,305172,307568#msg-307568 https://reprap.org/forum/read.php?215,305172,307568#msg-307568 www.photonlexicon.com]]]> VDX MetalicaRap Fri, 07 Feb 2014 08:40:28 -0500 https://reprap.org/forum/read.php?215,305172,306208#msg-306208 https://reprap.org/forum/read.php?215,305172,306208#msg-306208
Optical fiber lasers have been out for quite some time now (BTW, no relationship with fiberglass whatsoever). These are quite inexpensive if made in China. [en.wikipedia.org] [www.rp-photonics.com]
