Help with first laser?

    Hello. I'm fairly new to the Powder Toy, but I've already figured out how to make a working laser (among a few other things like nuclear reactions) but I'm having a hard time figuring out how to protect it. Whenever it's own photons are reflected back at it, not necessarily right through the barrel but when it touches any wall I make around the electronics, they just melt. Is there any material that is outright invincible and won't conduct heat to anything? Insulation just melts before it even gets close to the temperatures I need it to be solid when exposed to. Thanks.

    DMND under Solids is invincible. HSWC under Powered Materials is also invincible, HSWC is red, and DMND is blue, so take your pick.

    Thank you. I was a little confused because the DMND conducted the heat to the electronics and melting them anyway, but I tried making it just a protective casing with a layer of nothing between it and the electronics, and now it works perfectly.

     

    Also, it appears that photons going through the barrel don't damage it normally. However, when I try firing at some other materials, something, perhaps plasma, appears to come down the barrel from the target, and melts the electronics almost instantly. Is there some sort of filter particle I can put at the end, that lets light through but not physical particles?

     

    EDIT: I've found another problem. Apperantly, turning it on and off heats it up slightly, so it eventually melts when put under repeated use. Would you think there's a way of fixing this?

    You can use dead LIFE or clone LN2 or something next to whatever is heating up.

    hswc isnt invincible

    Just use 2 layers of INSL around each piece of wire.

     

    One tactic is to have each piece of PCLN a space apart, the very back of my lasers have PCLN Cloning INSL to protect the circuitry, A Tad hard to explain but I hope you get the idea.

     

    EDIT: It seems that you are firing at things from close range, I would recommend FILT at the end of your barrels surrounded by diamond at the front to protect the middle and rear of the weapon?

     As for the barrel problem, you can always direct the photons into an in portal (PRTI under Special) and place an out portal (PRTO under Special) where you want to shoot those protons. A good example is Amphealy's TSNS Laser Heater. (https://powdertoy.co.uk/Browse/View.html?ID=1009228)

     

    Now, for the electronics, instead of using METL for wires, use TTAN under Solids. It conducts electricity just the same, but it seems SPRK doesn't heat it at all, it consistantly keeps it's temperature at 22 degrees. Obviously, don't expose the TTAN to heat, or it will melt.

    You could also use a portal between the emitter and the heater. then you only have to worry about a little over 900c which doesn't do much to anything.

     It is invulnerable to most particles (Electrons, Photons, Neutrons, doesn't conduct electricity, etc. Anti-Matter destroys it, but I have yet to see someone use Anti-Matter in a laser...) and heat, and that is really all LogicAndAspiration needs it to be.

    Even though I can't publish it.
