    Convert Wavelength to Color

    Hey guys, I stumbled upon this app on wolframalpha where you can type in a wavelength in nm and it shows you an image of that color! Thought I'd share this with you all and post a little spectrum with 5 nm increments of our visible spectrum. Enjoy :beer: Wolfram|Alpha Widgets: "Convert...

    Just thought I'd share this

    Here's an excerpt from The Matrix: Reloaded The Oracle is like God, in that she is omniscient. Neo is "the one", like us humans, asking her questions about his path to salvation. This to me, further affirms the point of how religion is apocryphal and unsubstantiated. Christianity and Islam...

    Best Diodes for RGB

    So I have bought three dichroic mirrors for an RGB build I am going to make. I need some really good beam specs for the three diodes I am going for this project. I think I have some good ones narrowed down but I figured I would get some extra input as to which combination you guys would...

    600mW Yellow Laser Build

    So I just purchased these dichroic mirrors (link) to build a high power yellow laser by mixing red and green laser light. Here's a picture of what I hope will work, please let me know if you see any flaws :D So which red wavelength should I get 650nm or 638nm? Also what about the green...

    1 kW Laser

    I was thinking of saving up for a 1 kW laser rifle much like the one styropyro built in his video once I get my student loan paid off. What I would do differently would be to use NUBM44s focused independently with a G-2 lens', then much like styropyros to collimate them into one with a large...

    Who Won the First Presidential Debate?

    Whoever watched the entire debate cast your vote here :D :beer: and let us know who you think won and why. I personally think Trump won because he was more passionate on the crucial problems that face our country while Clinton was laughing most of the time. This is serious business and is no...

    Make Your Own Spectrometer for Under $1

    Spectrometers can be used to measure the wavelength of your laser. You can easily spend thousands of dollars on precision spectrometers, but for the hobbyist this one is incredibly cheap and fun to build. Granted the resolution is much lower but it still works just fine. Disclaimer: You must...

    Free Laser from Work :D

    Hey guys, so my boss just gave me this laser from our NIR instrument at work for free! :D She said it stopped working and the company didn't want to waste time fixing it so they just bought a new one :crackup: I am going to take it home and test it out and see if its the driver or the laser that...

    Which Green Laser Should I Get (cost aside)?

    I am in the market for a new diode for my next build project. I want the highest power green laser diode which from my quick research is 1W. I noticed there are two 1W diodes and also a 700mW one. The two 1W ones are the NUGM01 and NDG7475 and the 700mW one is the NDG700, all are 520nm in...

    Making a 485nm diode lol :p

    Since the 480-490nm diodes are somewhat of a unicorn nowadays I figured I'd go into research to make my own 485nm diode. I know the traditional 450nmish diode uses an InN-ZnN-GaN NIP junction which gives a bandgap of 2.75eV (=450nm). I was thinking if maybe we could switch out the GaN for TiO2...

    Using Host as a Wire

    So I noticed on several flashlights they connect the negative end of the battery from the spring to the entire laser host and use the host as a wire to connect to the negative end of the lamp. My question is this how I should do it if I am using two series feilong 32650s connected to an sxd...

    WTB: 10 Watt Laser Power Meter

    Anyone have a laser power meter that can measure up to 10 Watts and want to sell me it? I looked all over the internet and the cheapest one was like $900. Does anyone know of one for around $200?
