Can a laser be used to heat metal's to the point they glow red? How are laser cutters able to cut metal very easily? How much heat can a laser generate?

$\begingroup$ The answer is yes. You question is very basic. Please read wikipedia and coherent.com/applications/… and ask more questions. $\endgroup$– mcodesmartCommented Dec 9, 2013 at 19:50

2$\begingroup$ Discussions of "how much" is totally pointless without real values. How fast is a car? How long is a string? How big is a large rock? This unscientific nonsense doesn't belong here. $\endgroup$– Olin LathropCommented Dec 9, 2013 at 20:12

- Can a laser be used to heat metal's to the point they glow red?
Yes
- How much heat can a laser generate?
How big can it be? What laser are you talking about?
- How are laser cutters able to cut metal very easily?
Now that is a good question.
Some laser cutters will melt the object they are cutting to cut them. More sophisticated laser cutters, and more energy efficient, use ultra short pulses to create ablation. Ultra short pulsed laser ablation, typically converts a very specific amount of material into a plasma. This will allow scanning devices to verify the results before new pulse(s) are sent to cut more.

$\begingroup$ Ah a material is used, which explains it. There was a metal cutter that uses 150W, I saw that impossible that amount of power able to cut iron?! However, it seems that the CO2 played a role here. $\endgroup$– AxtIICommented Dec 10, 2013 at 1:42

$\begingroup$ The material I was talking about was the material to be cut. No material is used up other than the material cut, unless you include the wear and tear of time on the laser device. BTW: You probably want a solid state laser over a CO2 laser, but that all depends on what you plan to do, and how much you want to pay. Just saying a CO2 laser is like a light-bulb, a solid state laser is like a diode, which one do you think will last? $\endgroup$ Commented Dec 10, 2013 at 1:55

$\begingroup$ Laser can cut throw metal that easily? With low amounts of power that's remarkable. To think if it can cut throw the metal certainly it can heat it up super fast correct? $\endgroup$– AxtIICommented Dec 10, 2013 at 4:55

$\begingroup$ Yes, it will cut with precision. And it does not have to melt it, so the heat is used efficiently. Basically the metal in most cases will simply be warm to the touch afterward, not hot. $\endgroup$ Commented Dec 10, 2013 at 5:39

$\begingroup$ Well in that case, lasers are fast methods of heating metals super fast? I mean, if it can cut it that fast, certainly it can heat it up very quickly to the point where it glows. $\endgroup$– AxtIICommented Dec 10, 2013 at 6:35
