Hey guys so in a surplus store I recently discovered I found a whole box of these optical assemblies for crazy cheap. Perhaps somebody could help analyze it and help me decide what to do with it. Given the quality of the diode holders and the optics it might be worth the $15 just to salvage the...

Hello lpf! I love this site and have been lurking on and off for quite some time yet haven't posted very much as I never felt like i've had much to contribute before and was largely unsuccessful when I did. I find lasers mesmerizing, the physics fascinating and I love to tinker and make gadgets...

Hi guys! So recently i've been obsessed with the beautiful yellow/orange beamshots that i've seen posted around here and I really want to have a go at starting to assemble my own :D . Having just moved out to a place with a very tiny garage and only a simple bag of tools I just want to start out...

Hi guys...first want to thank everyone who helped me with my first build(~1W 445) by answering my questions and putting up with my nonsense :thanks: Now i pray your indulgence for a second time...I have an idea emerging from several thoughts swirling in my head and i want to bring it to the...

Hey guys. So I've been shopping around for a pair of m-140 diodes and being the frugal man I am :D I'm looking for the best deal possible since I'm buying two...what is the cheapest place to get then right now?

So i understand they are different wavelengths but as far as their input/output characteristics how do they compare? I know that they will both put out a lot of heat but want kind of power do they need? I have my eyes on a build using an m-140 and now i'm torn!! I will likely be using a smaller...

So i am in the process of putting together a 660nm 150-300mw laser that i hope will eventually burn things. So far i have: the diode, driver, glass lense, and module. I still need to decide on a host and then what i'm going to power it with. I have it all soldered together and i have it lasing...

Hi everyone i've been lurking and reading for several months while trying to scrape some cash together(im a student) to build a fun burning laser. Done a good bit of research and have bought a 660nm 150mw diode, module, glass lense, and driver from aixiz(chuck lives ten minutes from me :wave: )...
