The technological advancement of diode lasers is a global innovation by Alma. In addition to the classic 810 nm wavelength, Alma introduced additional wavelengths for permanent hair reduction through diode technology: 755 nm and the simultaneous combination of three technologies (Alexandrite 755 nm, Diode 810 nm, Nd:YAG 1064 nm) within a single applicator. Diode technology has also been developed at longer infrared wavelengths for surgical applications.
