5000W 2 in 1 Diode Laser Pico Machine – Upgradeable 6Bar+FAC to 10Bar, 4 to 6 Wavelengths | ZENI

Diode Laser Hair Removal

The 808nm diode handpiece targets melanin in the hair follicle. Clinical data in Fitzpatrick IV–VI skin shows 57.9% mean hair reduction in the underarm and 56.7% in the chin after three sessions, with 100% patient satisfaction and no cases of keloid formation, scarring, infection or pigmentary changes[reference:15]. The 4-wavelength starting configuration can be expanded to 6 wavelengths, allowing operators to tailor treatment across a broader range of skin types and hair colors as the clinic’s patient base diversifies. Common treatment areas include underarms, bikini line, legs, arms, back, chest and face. Multiple sessions are typically required because hair grows in cycles.

Picosecond Tattoo Removal

The picosecond handpiece delivers ultra-short pulses that shatter tattoo ink through a photoacoustic effect. Clinical comparisons demonstrate superior clearance versus nanosecond systems: 1064nm picosecond laser achieves 78.1% excellent clearance versus 54.4% for Q-switched nanosecond (p=0.029), with a median of 3 sessions versus 4 (p=0.020)[reference:16]. A 755nm randomized split-tattoo trial reported satisfactory clearance in 73.3% of picosecond cases versus 23.3% for nanosecond (p=0.0003), with higher clearance scores (VAS 8 vs. 5, p<0.0001)[reference:17]. A vacuum-assisted multimodal picosecond protocol reported mean pigment clearance exceeding 90% after a mean of 3.19 treatment sessions, with no severe long-term adverse events[reference:18]. Ink colour, depth and tattoo history affect treatment planning and the number of sessions required.

Pigment Removal & Skin Rejuvenation

The picosecond handpiece also addresses benign pigmented lesions, freckles, sun spots and uneven skin tone. The photoacoustic mechanism breaks pigment particles into smaller fragments for immune clearance. Depending on the wavelength configuration included with the selected package, the platform can support pigment-focused and skin rejuvenation protocols alongside hair and tattoo removal.

Scalable Treatment Capacity

The dual-axis upgrade path means treatment capacity and clinical breadth scale independently. A clinic focused on high-volume hair removal can upgrade Bar count first (6Bar+FAC to 10Bar) for faster coverage. A clinic serving a diverse patient demographic can upgrade wavelength count first (4 to 6) to match a broader range of chromophore absorption profiles. The two upgrades can also be combined as the practice grows in both volume and diversity.

Bar Upgrade: 6Bar+FAC → 10Bar

The diode laser stack can be configured as 6Bar+FAC or upgraded to 10Bar. More Bars increase total output power, supporting faster coverage of large body areas and more stable performance during extended sessions. The FAC (Fast Axis Collimation) lenses in the 6Bar+FAC configuration collimate the fast axis of each bar, improving fiber coupling efficiency. Experimental data shows coupling efficiency can reach 89% with properly aligned FAC optics, while a 4μm displacement error can reduce efficiency by 78.5%[reference:19][reference:20].

Wavelength Upgrade: 4 → 6

The platform starts with 4 wavelengths and can be upgraded to 6. Additional wavelengths expand the range of melanin absorption profiles and penetration depths available to the operator, which matters when treating a patient base that spans multiple Fitzpatrick skin types and hair colors. The specific wavelengths included in the 4- and 6-wavelength configurations should be confirmed in the quotation.

Picosecond Laser Mechanism

Picosecond lasers deliver pulses in the trillionths of a second, creating a photoacoustic pressure wave that shatters tattoo ink and pigment particles into smaller fragments. This mechanical fragmentation allows the body’s immune system to clear the particles more efficiently than purely photothermal nanosecond systems, which is why clinical comparisons consistently show higher excellent clearance rates and fewer sessions for picosecond lasers[reference:21][reference:22].

Per-handle output power, specific wavelength combinations for the 4- and 6-wavelength configurations, picosecond wavelength options, pulse duration, spot size, screen size, cooling system, dimensions, weight and voltage should be confirmed in the model-specific specification sheet for the selected Bar and wavelength configuration.

What are the two upgrade paths on this machine?

First, the diode laser stack can be configured as 6Bar+FAC or upgraded to 10Bar for higher total output power. Second, the wavelength count can expand from 4 wavelengths to 6 wavelengths for broader skin-type and hair-color coverage. The two upgrades are independent — a clinic can pursue one, the other, or both based on its service mix.

What clinical evidence supports the hair removal and tattoo removal applications?

For hair removal: 808nm diode laser achieves 57.9% mean hair reduction after three sessions in Fitzpatrick IV–VI skin, with 100% patient satisfaction and no cases of keloid formation, scarring, infection or pigmentary changes[reference:23]. For tattoo removal: 1064nm picosecond laser achieves 78.1% excellent clearance versus 54.4% for nanosecond systems, with fewer median sessions (3 vs. 4, p=0.020)[reference:24]; 755nm picosecond achieved satisfactory clearance in 73.3% of cases versus 23.3% for nanosecond (p=0.0003), with higher clearance scores (VAS 8 vs. 5, p<0.0001)[reference:25].

Why does FAC matter, and which configuration includes it?

FAC (Fast Axis Collimation) lenses collimate the fast axis of each laser bar, improving fiber coupling efficiency. Experimental data shows coupling efficiency can reach 89% with properly aligned FAC optics, and a 4μm displacement error can reduce efficiency by 78.5%[reference:26][reference:27]. The 6Bar+FAC configuration includes FAC. Whether the 10Bar configuration includes FAC should be confirmed in the quotation.

How does this differ from ZENI’s other 5000W 2-in-1 models?

The 5000W 2-in-1 with LCD ($1,360) emphasizes on-handle parameter control. The Dual Handle model ($1,499) emphasizes two independent handpieces for workflow switching. The Full-Body model ($1,360) emphasizes large-area coverage. This model ($1,449) is the only one in the 5000W series that explicitly combines Bar/FAC power upgrade (6Bar+FAC to 10Bar) with wavelength-count upgrade (4 to 6), making it the most flexible option for clinics that have not yet locked in their final service mix.

What should I request with the quotation?

Ask for the model-specific specification sheet covering the selected Bar configuration, the specific wavelengths included in the 4-wavelength and 6-wavelength options, picosecond wavelength configuration, per-handle output power, pulse duration, spot size, screen size, cooling system, dimensions, weight and voltage. Confirm the complete accessory list including both handpieces, protective eyewear and power cord. Verify CE or relevant certification documentation for your market.
