Chapter 3 – Fundamentals of Laser/IPL Hair Removal 2nd Edition
The measured wavelengths varied from the stated wavelengths – this is to allow the marketeers to make claims based on proper clinical studies with Alexandrite and Nd:YAG lasers. While the actual, measured wavelengths are not too far from their claimed values, it’s a bit ‘cheeky’!!
It would be very interesting to see the fluence outputs from some other systems to see if they account for the difference in melanin absorptions. If they don’t, then those systems may suffer from the same problem as the above device – a redundant wavelength! Most of the actual effectiveness will come from just the 755 and 810nm (or whatever they actually produce!)
Figure 114 - The measured wavelengths emitted by this particular device.
We’re not suggesting that all triple wavelength diode lasers do this, but we’re not surprised that at least one does.
Note – we recently learned that some of the diode systems which claim to have three or four wavelength outputs DO NOT!!! They only output one wavelength! It’s just marketing baloney again...
