Premium Alexandrite and Nd:YAG dual-wavelength lasers designed for maximum follicular destruction, zero downtime, and unmatched reliability.
The Alexandrite laser (755nm) operates as a solid-state laser system utilizing a chromium-doped chrysoberyl crystal ($BeAl_2O_4:Cr^{3+}$) as its gain medium. This specific active crystal structure produces electromagnetic radiation at a nominal wavelength of 755 nanometers. Within the optical absorption spectrum of human biological tissue, the 755nm wavelength exhibits an exceptionally high coefficient of absorption for melanin, while demonstrating a significantly lower absorption rate for water and hemoglobin compared to shorter wavelengths.
By targeting melanin, the optical energy converts to localized thermal energy within the hair follicle's shaft and bulb. This process, known as Selective Photothermolysis, ensures that the target chromophore is thermally disrupted without exceeding the thermal relaxation time (TRT) of the surrounding epidermal tissues. For dermatologist clinics and aesthetic distributors, this technology remains the gold standard for treating Fitzpatrick Skin Types I through IV, balancing safety with swift pigment clearance.
Compared to 808nm diode systems and 1064nm Nd:YAG lasers, the Alexandrite laser boasts superior melanin absorption capabilities:
