Matching Wavelength to Tattoo Pigment Colour on the Super Picosecond Laser Machine

The most common reason a tattoo removal session underperforms isn't the technology — it's a wavelength mismatched to the ink colour in front of the practitioner. Every pigment absorbs laser energy differently depending on its colour, and a single-wavelength device can only ever address part of a multi-coloured tattoo effectively. This is precisely the problem a multi-wavelength platform is built to solve — provided the practitioner knows which wavelength to select for which colour.

This guide maps the Super Picosecond Laser Machine's wavelength range to the specific pigment colours each is built to target, so practitioners can select confidently rather than guessing at parameters for a multi-coloured or unfamiliar tattoo.

Why Wavelength Determines Which Colours Respond

Tattoo ink pigments absorb laser light selectively based on their colour — each pigment has a wavelength range where its absorption is strongest, and treating a pigment with a poorly matched wavelength produces weak or negligible clearance regardless of how much energy is delivered. This is the same selective-absorption principle behind all laser-tissue interaction: the laser's photoacoustic effect can only fragment the pigment if the wavelength is actually absorbed by that specific colour of ink.[1]

This is precisely why multi-coloured tattoos require a multi-wavelength platform to treat effectively — a single-wavelength device may clear the colours that happen to match its wavelength while leaving others largely untouched, an outcome that reflects the physics of pigment absorption rather than a failure of technique.

Wavelength-to-Pigment Guide

1064nm — Dark tattoo pigments — The longest of the standard wavelengths, 1064nm is the primary choice for black and other dark pigments, the most common tattoo ink colour. Its longer wavelength also carries lower epidermal melanin absorption, which is a relevant consideration for treatment on darker Fitzpatrick skin types.

532nm — Light-coloured tattoo pigments — At the shorter end of the standard wavelength range, 532nm targets lighter pigment colours that 1064nm does not effectively address, making it the complementary wavelength for multi-coloured tattoo work alongside 1064nm.

585nm (optional) — Red tattoo pigments and uneven skin tone — Red ink is notoriously difficult to clear with standard tattoo removal wavelengths; the optional 585nm wavelength extends the platform's range specifically to address red pigment, along with applications for uneven skin tone.

640nm (optional) — Green and purple tattoo pigments — Green and purple inks are similarly resistant to standard wavelengths; the optional 640nm addition extends coverage to these specific colours, rounding out the platform's ability to address the full range of pigments found in modern multi-coloured tattoo work.

The Bottom Line

Wavelength selection is the single most consequential decision in tattoo removal, and it's determined entirely by pigment colour, not practitioner preference. The Super Picosecond's five-wavelength range — 1064nm and 532nm for dark and light pigments, with 755nm for general dermal targets, plus optional 585nm and 640nm for red and green/purple ink — gives practitioners the coverage to plan a genuinely effective multi-session course for even the most complex, multi-coloured tattoo work.
