5000W 2 in 1 Diode Laser Pico Machine – Upgradeable 6Bar+FAC to 16Bar+FAC | ZENI

Diode Laser Hair Removal

The 808nm diode laser 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[reference:15]. Hair regrowth time extends progressively with repeated sessions, from 8 days after the first treatment to 33.7 days after the twelfth[reference:16]. Triple-wavelength diode configurations (755/808/1064nm) have achieved 39.7% excellent GAIS responses, significantly higher than IPL at 20.0%[reference:17]. 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 studies demonstrate superior clearance compared to 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:18]. 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:19]. 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 upgradeable Bar/FAC configuration means treatment capacity scales with clinic growth. A low-to-moderate volume clinic can start with 6Bar+FAC or 10Bar; a high-volume clinic can opt for 10Bar+FAC or 16Bar+FAC for faster coverage and more stable output during back-to-back sessions. The same platform serves both scenarios without forcing an all-or-nothing purchasing decision.

808nm Diode Laser & FAC Technology

Diode laser hair removal relies on selective photothermolysis: 808nm near-infrared light is absorbed by melanin in the hair follicle, converting to heat that impairs regrowth. FAC (Fast Axis Collimation) lenses are placed in front of each laser bar to collimate the fast axis of the emitted beam. Without FAC or with misaligned FAC, diode-to-fiber coupling efficiency is typically in the range of approximately 50%–60%; with properly aligned FAC lenses, coupling efficiency increases to approximately 85%–90% or more[reference:20]. This means more energy reaches the treatment site and less is lost as heat inside the handpiece. FAC also reduces laser diode junction temperatures, improving long-term stability and lifespan[reference:21].

Picosecond Laser Mechanism

Picosecond lasers deliver pulses in the trillionths of a second, creating a photoacoustic (pressure wave) effect 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. Clinical comparisons consistently show higher excellent clearance rates and fewer sessions for picosecond lasers in tattoo removal[reference:22].

Upgrade Path: From 6Bar+FAC to 16Bar+FAC

The 5000W power supply is the fixed foundation. The diode laser stack is the variable. A clinic can select 6Bar+FAC as a starting configuration, then upgrade to 10Bar, 10Bar+FAC or 16Bar+FAC as treatment volume increases. Each upgrade increases total output power and, in the FAC configurations, maintains or improves beam quality and coupling efficiency. This modular approach avoids the need to replace the entire console when higher power is required. Learn more about laser-based treatment systems for clinical background.

Diode wavelength configuration, picosecond wavelength options, per-handle output power, pulse duration, spot size, screen size, cooling system, dimensions, weight and voltage should be confirmed in the model-specific specification sheet. Industry-typical 5000W 2-in-1 systems include 755/808/940/1064nm diode wavelengths, 532/1064/1320nm picosecond options, and a 15.6-inch touchscreen.

What does “upgradeable to 6Bar+FAC, 10Bar, 10Bar+FAC or 16Bar+FAC” mean?

It means the diode laser stack inside the handpiece can be configured or upgraded across four options. 6Bar+FAC is the entry configuration; 10Bar increases total power without FAC; 10Bar+FAC combines higher power with FAC collimation; 16Bar+FAC delivers the highest power with FAC. The 5000W power supply supports all four configurations. Clinics can start with a base option and upgrade later without replacing the entire console.

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 hair regrowth time extending from 8 days to 33.7 days after twelve sessions[reference:23][reference:24]. 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:25]. A vacuum-assisted multimodal picosecond protocol reported mean pigment clearance exceeding 90% after a mean of 3.19 sessions[reference:26].

Why does FAC matter in a diode laser system?

FAC (Fast Axis Collimation) lenses collimate the fast axis of each laser bar, improving diode-to-fiber coupling efficiency from approximately 50%–60% to approximately 85%–90% or more[reference:27]. This means more laser energy reaches the skin and less is lost as heat inside the handpiece. FAC also reduces junction temperatures, improving long-term stability. The 10Bar+FAC and 16Bar+FAC configurations include FAC; the 10Bar configuration does not.

Can both handpieces operate at the same time?

No. The diode and picosecond handpieces serve different treatment functions and are used sequentially. Only one handpiece operates per treatment session. The 2-in-1 designation refers to two laser modalities sharing one console, not simultaneous output.

What should I request with the quotation?

Ask for the model-specific specification sheet covering the exact Bar/FAC configuration you are considering, diode wavelength combination, picosecond wavelength options, 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.
