Wavelengths and Skin Types
The Alexandrite laser operates at 755 nm – ideal for fair skin (Fitzpatrick I–III) and fine to medium hair. However, for darker skin tones, the risk of burns and hyperpigmentation increases significantly.
Modern Triple-Wavelength Diode lasers cover 755/808/1064 nm, allowing them to safely treat all skin types I–VI, including tanned and ethnic skin.
Speed, Maintenance, and Total Cost of Ownership
For a clinic serving a broad patient demographic, a Triple-Wavelength Diode laser is in most cases the more economically and medically flexible choice.
- Spot Size: Diode lasers up to 12×24 mm – faster for large treatment areas.
- Maintenance: Alexandrite devices require regular crystal replacement – more expensive over the lifecycle.
- Service Network: In the DACH region, the supply of spare parts for Diode lasers is significantly better.
- Acquisition: Premium Alexandrite starting from approx. 35,000 EUR; Triple-Wavelength Diode lasers starting from 18,000 EUR.
FAQ
Frequently asked questions
Is Alexandrite more painful than Diode?
Generally, yes – the shorter wavelength is absorbed more intensely. Modern Diode lasers equipped with contact cooling are typically more comfortable for the patient.
Which laser is better for tanned skin?
Clearly the Triple-Wavelength Diode laser due to its 1064 nm Nd:YAG component.
