Hello and welcome to Ask a Doctor service.
I have gone through your query and noted your concern.

Yes, Low Level.Laser (LLLT) does have a role in various conditions including hair loss. The most commonly used devices have wavelengths in the range 500–1,100 nm. Home-use LLLT devices are also available that stimulate growth.

The Hairmax Lasercomb is US FDA approved as a safe therapy for the treatment of male pattern hair loss/ AGA.

Hope I have answered your query.

Detailed Answer:
Hi
That is a bit of a technical question A laser engineer would be better able to answer that. The laser fluence or energy (J/cm2) and power (Watts) are defined for the purpose it is used for and it is governed by laser diodes.
Take care
