Nd:YAP/KTP 540/1079 nm (Q-Switched) — Dual-Wavelength Emitter

Overview
This compact emitter plugs into the MULTILINE™ base unit and delivers two wavelengths: 540 nm and 1079 nm. It supports three distinct treatment families on one platform—vascular, tattoo, and hair removal—with unique regimes and clinical protocols for each.

Vascular treatments — Target Creation Technology® (TCT)

What it’s for
Facial and leg telangiectasias, hemangiomas, and rosacea-related networks. (Not a therapy for varicose vein disease—this requires another laser emitter – Nd:YAP 3-Wave Scalpel.)

How it works
TCT stages the action in microseconds:

• 540 nm engages hemoglobin to create a highly absorptive intravascular “target.”
• 1079 nm then couples to that target to complete vessel coagulation with high selectivity and a lower epidermal load.

On-table endpoint
Visible vessel darkening along its course. “Instant disappearance” is not required and often not desirable.

Tattoo removal — Deep Acoustic Wave™ workflows

What it’s for
Professional and amateur tattoos, including multicolor designs.

How it works
DAW uses pulse-train photoacoustics to fragment pigment layer-by-layer so deeper ink becomes accessible in the same pass. This emitter contributes:

• 540 nm for reds/oranges and some warm tones.
• 1079 nm (near-IR, similar use to 1064 nm) for black/blue pigments.

For stubborn greens and additional blues, clinics typically add 755 nm Alexandrite and/or 694 nm Ruby emitters on the same platform.

Course
Multiple sessions are normal; spacing depends on ink density, color, and skin type.

Hair removal — QOOL-epilation® at 1079 nm

What it’s for
Comfortable hair reduction on the face and body across all skin phototypes, including tanned skin.

How it works
The 1079 nm laser source delivers millisecond-long trains of nanosecond pulses. Energy concentrates inside the hair shaft while the gaps let surrounding skin cool, heating the bulb/bulge with minimal skin burden.

Note: 540 nm is not used for epilation.

On-table endpoint
Treated hairs typically whiten and curl; skin remains calm. Hairs shed over the following days to weeks. No anaesthesia or contact cooling is typically required.

Key specifications 

Wavelengths: 540 nm and 1079 nm (Q-switched)

• Pulse format: nanosecond micro-pulses (single shots or pulse trains, program-dependent)
• Spot sizes: ~3–8 mm
• Repetition rate: up to ~1–5 Hz (by program/area)

Why clinics choose this emitter

• True versatility, clear protocols: one compact head supports three high-value services without mixing indications.
• Selective, efficient treatments: staged dual-wavelength logic for vessels; color-matched wavelengths for tattoos; hair-focused pulse trains for epilation.
• Platform simplicity: swap emitters as needed while keeping the same base unit, presets, and training workflow.
