Long-pulse Nd:YAG laser

The Pmise LN-01 is a long-pulse Nd:YAG laser built for two of the busiest tickets in aesthetic practice: hair removal and vascular lesion treatment, with skin rejuvenation as a useful third service. Its 1064 nm beam penetrates deeper than most aesthetic wavelengths, and that depth is exactly why clinics treating darker skin keep specifying long-pulse Nd:YAG. A 532 nm output is available as an option for work closer to the surface.

Picture where this machine earns its keep. A clinic with a mixed patient base can't rely on wavelengths that struggle past Fitzpatrick III, and long-pulse 1064 nm has long been the accepted answer for hair removal on types IV to VI. The same beam also reaches vessels that shorter wavelengths never touch. One platform, two dependable revenue streams.

To be clear, this is professional equipment for trained operators, not a home device. We support every LN-01 with installation guidance, operator training materials, and spare parts through our service team.

How it works

The working principle is selective photothermolysis, described by Anderson and Parrish back in 1983 and still the foundation of laser dermatology. Choose a wavelength your target absorbs strongly while nearby tissue mostly ignores it, deliver enough energy fast enough, and the target breaks down while its surroundings stay intact.

At 1064 nm the key absorbers are hemoglobin in blood vessels and melanin in the follicular bulb. Epidermal melanin takes up comparatively little at this wavelength, which is what makes darker skin treatable in practice. The beam passes through the surface, reaches the target vessel or follicle, and with sufficient energy density damages that structure without wounding the epidermis. Our device manuals state it plainly: surrounding normal tissue absorbs very little or none.

Cooling handles the rest of the safety equation. The handpiece uses sapphire contact cooling to draw heat out of the epidermis while you fire, so the fluences these indications genuinely need stay tolerable at the surface. Energy also travels by direct output rather than fiber delivery, an arrangement our engineering archive credits with avoiding a meaningful share of transmission loss between laser and skin.

Applications

Hair removal, including Fitzpatrick skin types IV to VI where shorter wavelengths carry higher epidermal risk
Vascular lesion treatment, helping improve visible vessels such as facial telangiectasias and spider veins
Skin rejuvenation as a complementary, low-downtime add-on service

Who should buy it? Laser clinics and medspas serving diverse skin tones, plus distributors who need a dependable long-pulse Nd:YAG in their catalogue. If high-volume hair removal on lighter skin is your core business, pair it with our DL-07 diode laser; plenty of buyers run both. For the clinical background, see our pages on laser hair removal and vascular lesions.

Key advantages

Compressor-based cooling system keeps the laser stable through long clinic days instead of forcing rest breaks between patients
Sapphire-cooled treatment handpiece with adjustable spot sizes, so you match the spot to the lesion rather than the other way round
Direct energy output reduces transmission loss compared with fiber-delivered designs
Straightforward operating interface that new staff pick up quickly
Compact vertical build that doesn't swallow a treatment room

Nothing here is exotic, and that's deliberate. Buyers of long-pulse Nd:YAG want a proven wavelength, honest thermal management, and a machine their team can run confidently on day one. That's what the LN-01 delivers.

Frequently asked questions

Which skin types can the LN-01 treat?

Long-pulse 1064 nm is the go-to wavelength for hair removal on darker skin, and our manuals note its suitability for Fitzpatrick types IV to VI in particular. Lighter types respond too. Epidermal melanin absorbs relatively little at this wavelength, which lowers surface risk, though operators still need to screen for recent tanning and adjust settings per patient.

How many sessions does hair removal take?

More than one, always. Hair grows in cycles and the laser only disables follicles in the active growth phase, so patients need a course of treatments spaced weeks apart. The exact count depends on body area, hair density, and skin type. We'd advise your consultation staff to set that expectation early rather than promise a fixed number.

What safety measures does the machine include?

Sapphire contact cooling protects the epidermis during firing, and the system provides an interlock connection, an emergency stop, and key-switch control. This is a Class 4 laser, so protective eyewear for operator and patient is mandatory. The manual also lists screening contraindications, including pregnancy, active skin infection, keloid history, and recent sun exposure.

What about training and warranty?

Every purchase includes free technical training from our clinical instructors, plus phone follow-up support afterwards. The standard warranty covers defects in materials and workmanship under normal use for one year, and spare parts remain available beyond that. Ask us on the contact page for lead times and distributor terms in your market.
