Honestly, I knew it wasn't the laser that detected temperature. Though I was not aware of the spectrum being the decisive fact on its heating factor. So ideally you want something in the ultraviolet as opposed to the IR spectrum. Makes sense when you're talking about wavelengths. I should have...
Would it be possible to build a more laser module like an infrared thermometer that could heat something or burn while measuring it? Or can lasers not reliably measure the ambient temperature at those higher levels than an infrared thermometer? I don't want something super crazy just a 5 -7mw. I...
