Which technology is used in tria 4x?

Hi Thank you for your open question in here. I do not want to make them weak just by using IPL or Elight devices. The most effective device for me is Diod laser ( I did it 3 times with my doctor in her clinic with diod device and the results was very very good ). Now I want to buy a home laser hair removal. Someone told me that diod technology is used just in tria x4 between all of home laser hair removal. Would you please kindly tell me is that true? Thank you for your time.
