Picosecond Laser Science

How picosecond pulses fragment tattoo ink and pigment, why wavelength and pulse duration matter, and the treatment menu a multi-modality pico platform opens for a clinic.

What makes a picosecond laser different?

A picosecond laser fires pulses roughly a thousand times shorter than a Q-switched nanosecond laser. The shorter pulse drives a stronger photoacoustic effect that fragments tattoo ink and pigment into finer particles the body can clear. A platform that leads with 1064 nm, adds 532 nm and layers in long-pulse and fractional modes covers tattoo, PMU, pigment, texture and skin-quality work across skin types.

FAQs

What is the difference between a picosecond and a Q-switched laser?

Both deliver high-energy pulses to fragment pigment, but the picosecond pulse is roughly a thousand times shorter than a Q-switched nanosecond pulse. The shorter pulse increases the photoacoustic (pressure) effect, fragmenting pigment into finer particles the body can clear.

Why does wavelength matter on a picosecond laser?

1064 nm penetrates deeper with lower melanin absorption, which is why it is used across a broad range of skin types; shorter wavelengths are absorbed more strongly by surface melanin. A platform that leads with 1064 nm and adds 532 nm covers more pigment and tattoo work across skin types.

Is a 500 ps pulse better than a 750 ps pulse?

At the same energy, a 500 ps pulse delivers higher peak power, because peak power is energy divided by pulse duration. Higher peak power increases the photoacoustic effect that fragments pigment. Pulse width is one important factor alongside wavelength, delivered energy and spot size.

Can a picosecond laser remove tattoos on darker skin?

Yes — 1064 nm picosecond delivery is the wavelength used for darker skin. In published studies, 1064 nm picosecond tattoo removal was associated with effective clearance and a low rate of long-term pigment changes in skin types III–IV.

Can a picosecond laser treat melasma?

It is used in conservative, provider-guided melasma protocols. Published studies report that 1064 nm picosecond laser can improve melasma, though results vary and may be comparable to established treatments. It is not a cure, and melasma is recurrence-prone.

What can the Pro 1 Pico treat?

Tattoos, PMU, pigment and sun damage, melasma-prone skin with conservative provider-guided protocols, redness and veins, pores, acne scars and texture, and year-round skin quality — plus selected hair-reduction protocols with the long-pulse mode.

  • Pico Laser Training: Why Pulse Duration Matters — Pulse duration is what makes pico worth buying — picosecond vs nanosecond Q-switched, and why shorter pulses power pigment, tattoo and melasma work.
  • Pico Laser Training: Tattoo Colour and Wavelength Selection — Match wavelength to ink and skin and every tattoo becomes a bookable case — black, red, orange, green, blue and cosmetic inks on one pico platform.
  • Why 532 nm Requires Caution on Darker Skin Types — Treat darker skin with confidence: why 532 nm needs caution, how PIH and melasma risk shape the plan, and when 1064 nm is the conservative lead.
  • Why PMU Removal Is Not the Same as Tattoo Removal — PMU removal is a premium facial-correction service, not tattoo removal on the face — pigment chemistry, oxidation risk and the pico protocols that win it.
