In summary, the conversation discusses whether there are any differences in the properties, efficacy, and side effects of 1064 nm light emitted by Long-Pulsed Diode laser device and Long-Pulsed Nd:YAG laser device for hair removal, assuming that the fluences, pulse durations, and spot sizes of both devices are exactly the same. It is suggested that, neglecting their coherence property, the two lasers should have the same energy per pulse and therefore exhibit similar interactions with matter. However, it is also noted that laser fluence is related to the overall amount of energy delivered, and further data and studies are needed to fully compare the effectiveness of the two light sources.

Are there any differences between 1064 nm emitted by Long-Pulsed Diode laser device and 1064 nm emitted by Long-Pulsed Nd:YAG laser device for hair removal?

Assume that fluences, pulse durations & spot sizes of both devices are exactly the same, should the property, efficacy and side effects of the 1064-nm light be the same no matter what sources it comes from? Shouldn't it?

Neglecting their coherence property, given the condition you assume then the two lasers should have the same energy per pulse. I expect they won't exhibit appreciable difference in the way they interact with matter.

Welcome to the PF. :smile:

Laser fluence is related to the overall amount of energy delivered by the pulse. I don't think you can assume that the light intensity versus time is the same just because the fluences are the same. Do you have any data showing the laser light flux versus time for each of those pulse sources?

Has the FDA approved devices that use each of those light sources? Are there any clinical studies comparing their effectiveness to each other?
