Nd:YAG Laser Treatments Explained: One Wavelength, Many Uses
Few wavelengths appear across as many aesthetic treatments as the 1064 nm Nd:YAG. It shows up in hair removal, vascular treatment, pigment toning, and tattoo removal — sometimes on the very same platform. Understanding why one wavelength stretches so far comes down to how it interacts with skin and how its pulse is shaped.
Why 1064 nm is so versatile
The 1064 nm wavelength penetrates relatively deeply and is absorbed less by the melanin in the epidermis than shorter wavelengths. That combination lets it reach deeper targets — follicles, vessels, and pigment — while being gentler on the surface, which is why it is often the preferred choice for darker skin types. What it treats on any given day depends largely on how long the pulse lasts.
Long-pulsed Nd:YAG: hair and vessels
In its long-pulsed form, Nd:YAG heats structures over milliseconds — long enough to disable a hair follicle or collapse a blood vessel. That makes it a common choice for hair removal on darker skin and coarser hair, and for deeper vascular targets such as leg veins. WONTECH's SANDRO DUAL pairs 1064 nm with a 755 nm Alexandrite wavelength for hair removal across skin types, and the V-LASER combines 1064 nm with 532 nm KTP for vascular work.
Q-switched and picosecond Nd:YAG: pigment and tattoos
Shorten the pulse to nanoseconds or picoseconds and the same wavelength does something different — it fractures pigment and tattoo ink so the body can clear it, with far less heat delivered to surrounding tissue. WONTECH's PASTELLE PRO uses Q-switched Nd:YAG for toning and pigment, and PICO MAJESTY delivers a 250-picosecond 1064 nm pulse for demanding tattoo and pigment work.
One wavelength, different pulses
- Long-pulsed (milliseconds): hair removal and vascular treatment.
- Q-switched (nanoseconds): pigment toning and tattoo removal.
- Picosecond (trillionths of a second): resistant or multi-colored ink and conservative pigment work.
- Companion wavelengths (532 nm, 755 nm) extend the range a single platform can cover.
- Across all forms, 1064 nm is generally better tolerated across a wider range of skin types.
Choosing a platform
Because the pulse determines the application, the right question is not just whether a platform offers Nd:YAG, but which form of it — and which companion wavelengths — match the treatments you want to grow. Many practices end up wanting 1064 nm in more than one form across their device menu.
These systems are intended for use by licensed medical professionals, and individual results vary. A hands-on demo is the best way to see how a given Nd:YAG platform performs on the cases you treat most.
