Hello all,
I was wondering if you could help me with a laser question, I was looking at using a laser diode as a heating element.
I was wondering how much power it would take to heat a thin piece of copper about the size of a 5 or 10c coin and as thin as say a couple of pieces of paper, to 200 degrees Celsius approx. (the laser can be near or better still touching the copper, creating an enclosed heating element)
I was interested to know if this would be achievable within perhaps a 5 or 6sec time frame, how much power would be needed (could it be done with mains AC 240v, 12v DC or perhaps even just a couple of aa battery) And also what would be the cheapest laser and lens assembly that would be able to achieve this without self-destructing?
If it is cost effective to do so i would like to do some experiments with such a laser to see if it would suit my purpose, how much would i be looking at for such a laser and what would a typical life span be if producing heat at those temps?
If anyone has or can make a laser and driver assembly that could be suitable id love to buy one ready made, im a computer tech and have a good understanding of electronics in general but lasers i only have a basic understanding of, optic's and radiation are not really my thing.
I have seen demo's on the net of blu-ray laser diodes being used to heat objects but we cant believe everything we see on youtube :can: The ultimate source for Lasers and Accessories have a kit for $100 that they show mounted in a bic lighter but they have no specs on the heat that could be expected to be produced so i was a bit skeptical.
Im betting that most of you would have successfully produced the kind of temps i am wanting to achieve, any help would be much appreciated.
Regards,
Jon.
