They changed their 589nm options, and were out of stock of a bunch of things, now the laser pointer section shows "page not found". If this is true that would be really unfortunate. They had really nice lasers particularly 589nm and their GLP 532nm pointers. Also other than laserglow which is...

Welcome! Find it a bit odd your willing to show your face but not your name. Regardless I'm sure you'll find a lot of helpful info here on LPF.

Do you know what diodes it uses?

What is the minimum output for each color? Could I do 5mW for each diode? What is the divergence of each diode? What is the divergence as a whole? What do the vials do? Is the basic plan worth it? Thanks

How much are you willing to spend? Pm me.

As long as the beams are contained within the harp as the above post mentioned, I don't see 50mW being an issue and would give a much better experience.

Does the sanwu beam expander need either of the adapters they sell? Also in the last host how much would it be if the brass was replaced with copper?

They gotta use a yellow laser just to flex.... Lol

Go to this website click on each wavelength, and if it doesn't specifically say its a diode laser (such as if it says solid state) at the top then its DPSS. Have fun.

Unless you point it a black text, no. The higher the wavelength the more sensitive it is to what color the thing your burning is. So therefore red is pretty much the worst choice.

White paper probably 300-500mW. Black paper probably 75mW will make it smoke. Igniting paper if you take something printed on normal printer paper and burn the back text can be done with 200mW but takes some effort. All of these assume the laser is focused and held still. Wavelength (color)...

Yes, the LPM measures based on how much heat the laser produces on the thermopile. And also the laser itself is inherently unstable due to voltage, and temperature fluctuations. You can overcome this to an extent with a lab laser though.

Your probably fine, but if you want to be safe see an eye doctor. And don't forget to throw your friends laser in the garbage because nothing good will come of it.

How much did his laser cost (yes this is a relavent question)

Would be way too unreliable. Lasers measure more of a difference than that measuring them 1 minute apart. I don't know if the laser is unstable or if it's the LPM. Maybe it could be done with a lab laser and an lpm in an extremely temperature controlled environment, but with just regular...

Pretty sure your best bet would be either a 500mW 405nm (don't remember which diode). Or a high power dpss (such as 532nm). An 800mW that usually runs at 1W can be purchased from jetlasers for $460. Whichever you choose, a beam expander will make it even better. Also beam intensity doesn't...

That's unfortunate the interface only goes to 4W, it's really downplaying what that head is capable of, especially with he heatsink. Also just a heads up, I tried to sell my similar unit for $500 for just about a year and the highest offer I got was $350 I believe. I ended up selling it for...

See how it burns various things, black foam, black plastic, matches, dark balloons. And let us know your results, that will give you a rough idea of the output power. Just don't stare directly at the spot you are burning, look away. Safety goggles would be best but your laser probably isn't...

This thread is 8 years old... but the best quality green laser for under $40 is the laserglow anser, assuming you are only concerned with quality and not output. It may only be 5mW but that makes it legal which is nice and you don't have to be as careful with it as you would with other lasers...

Yes if that's a risk your willing to take. I will not be held responsible for customs.
