Pmise QE-01

How it works

A Q-switch stores energy in the laser cavity and releases it in a single 6-nanosecond burst. At that timescale the pulse is shorter than the thermal relaxation time of tattoo ink particles and melanosomes, so they are shattered photoacoustically before surrounding tissue meaningfully heats. The fragments are then cleared by the body's own scavenger cells over the following weeks.

The two wavelengths split the work by depth and colour. 1064nm penetrates deeper and is absorbed poorly by epidermal melanin, making it the safe choice for dermal pigment: black and blue ink, nevus of Ota, dermal melanocytosis. The 532nm frequency-doubled line is absorbed strongly near the surface, where it clears red and warm-toned inks and epidermal lesions like freckles. This is selective photothermolysis applied at nanosecond scale.

Applications

• Tattoo removal across ink colours: 1064nm for black and blue, 532nm for red and warm tones
• Nevus of Ota and dermal pigmented lesions with 1064nm, sessions spaced months apart
• Freckles, lentigines and epidermal sun spots with 532nm
• Laser toning protocols for pigment management under medical supervision

Key advantages

• Genuine EO Q-switch at 6ns, not a long-pulse imitation marketed as tattoo removal
• 800mJ at 1064nm and 400mJ at 532nm, enough for dense professional ink
• Spot size 1-7mm continuously adjustable to hold fluence at depth
• 1-10Hz repetition for practical session times on large pieces
• 7-joint articulated arm with a balanced handpiece for precision work
• Dual-voltage supply for 220V and 110V markets
