Well, I saw in some papers that the diode laser would be the best one. The mix is air + burned oil so it would be on gas phase.
I want to know how can I determine the energy that is leaving the laser and the energy received on a photoresistor or any other kind of receiver so I can compare.
I appreciate your reviews and doubts and I will try to analyze it in order to see if it is feasible.
If you have any suggestion or other options please tell me, it will only help.
