If you shine two lasers at the same spot that are the same frequency, and; exactly out of phase; would there still be energy at the one spot they are pointed at?
Bullington said:Ah, I see, so I will rephrase the question; if we shine two lasers with equal frequency, at the same spot and they don't interfere with each others path, what could the energy at that one spot be?
Well, I would think it wouldn't be double, maybe if the lasers interfered constructively then I would say the energy would increase, but two lasers on the same spot without any interference, that doubles? This is a new topic for me so I'd like to look into it a bit more, is there any reference for the energy being double?pixel said:Just curious why you would think, without interference, that it would be anything other than double?
Elsewhere is the short answer. The best one might do to exactly overlap two destructively canceling beams is likely feeding two ports of a 4 port beam splitter. In this case all the power would exit one port while none would go out the other (canceling one). Beam splitters conserve energy so it all balances when the numbers are worked.mrspeedybob said:If it less, then where did the non-absorbed energy go?
Ah, this is interesting,mrspeedybob said:Even if the 2 beams do interfere with each other destructively, the energy absorbed by the target should still be the sum of the 2 beams.
If it less, then where did the non-absorbed energy go?
Heating with two lasers results in a higher overall energy output compared to using just one laser. This is because the energy from each laser is combined, resulting in a larger amount of heat being delivered.
No, using two lasers will not necessarily double the temperature. The temperature increase will depend on the specific output power and wavelength of each laser, as well as the properties of the material being heated.
Yes, using two lasers can potentially cause uneven heating if they are not properly aligned or if there are variations in the material being heated. It is important to carefully control the output of each laser to ensure even heating.
Yes, there are safety concerns when using lasers for any application. It is important to follow proper safety protocols and wear appropriate protective gear when working with lasers to avoid potential harm to yourself and others.
Yes, using two lasers can provide several advantages, such as faster and more efficient heating, the ability to heat larger or more complex materials, and the potential for more precise and controlled heating. However, it also requires more advanced equipment and careful calibration to achieve optimal results.
