Explore our industrial-grade laser stack arrays and diode modules engineered specifically for handle repairs, upgrades, and high-duty cycle aesthetic platforms.
Established as a premier technological hub in central China, Xi'an Prima Beauty Equipment Co., Ltd. has spent more than a decade defining the benchmarks for high-performance laser beauty equipment. Our footprint spans across R&D labs, ISO-certified fabrication zones, and international compliance sectors, making us a key supplier in the field of aesthetic and medical laser technology.
By vertically integrating the entire production process—from basic semiconductor laser chip encapsulation to solid-state laser module design, diode stacks assembly, and whole-system outer cabinet development—we offer complete OEM/ODM solutions. Our main product catalog ranges from high-energy Diode Hair Removal Platforms, CO2 Fractional Lasers, and high-frequency Q-Switched Solid-State lasers to advanced Pico Laser systems.
In the global medical aesthetics sector, Picosecond Laser Technology represents a major advancement in dermatologist-grade skin therapies. Unlike traditional nanosecond Q-switched lasers, which rely heavily on photothermal action to heat up and break down melanin, modern Pico Lasers utilize Photoacoustic Shockwaves. This approach delivers ultra-short pulses (measured in trillionths of a second) to shatter targeted pigments with minimal thermal damage to surrounding tissue structures.
The transition from Q-switched nanosecond Nd:YAG lasers to advanced picosecond configurations has redefined clinical outcomes for tattoo removal, hyperpigmentation treatments, and non-ablative skin resurfacing. In nanosecond pulses, the mechanism of target destruction is thermal relaxation. If a target particle has a thermal relaxation time shorter than the pulse width, heat escapes into the surrounding dermis, potentially causing post-inflammatory hyperpigmentation (PIH), blistering, or scarring.
By compressing the pulse width to under 750 picoseconds (and in premium systems down to 450 picoseconds), the laser energy creates rapid thermal expansion within the pigment particle. This induces an acoustic pressure wave that fractures the target into micro-particles. These smaller fragments are more easily cleared by the body's lymphatic system, resulting in faster clearance rates and fewer required treatment sessions.
| Performance Metric | Nanosecond Lasers (Traditional Q-Switch) | Picosecond Lasers (Modern Platforms) |
|---|---|---|
| Pulse Duration | 5 - 20 Nanoseconds (10-9s) | 350 - 750 Picoseconds (10-12s) |
| Primary Target Mechanism | Photothermal (Heat Accumulation) | Photoacoustic (Pressure Shockwaves) |
| Melanin Particle Size Post-Treatment | Pebble-sized fragments | Fine dust particles |
| Risk of Post-Inflammatory Hyperpigmentation | Moderate to High (Skin Type IV-VI) | Very Low (Safe for diverse skin types) |
| Average Treatment Sessions Required | 10 - 15 sessions | 4 - 8 sessions |
The stability of a Picosecond system is fundamentally determined by its optical design and component durability. As a leading developer of semiconductor laser technologies, Xi'an Prima integrates laser chip fabrication directly with downstream manufacturing processes. This vertical structure addresses several common failure points in aesthetic devices:
International distributors and clinical groups face complex technical considerations when importing laser platforms from Chinese manufacturers. The procurement process typically centers on three main criteria:
To deliver picosecond pulses from the internal optical bench to the patient's skin, systems require high-quality delivery pathways. High-end systems utilize imported 7-joint articulated arms (often sourced from Korea or Japan) with internal gold-coated mirrors. These arms must maintain precise optical alignment across different angles, keeping energy loss below 10% between the resonator output and the handpiece.
A common issue with entry-level laser systems is energy fluctuation over extended operating sessions. High-end platforms integrate closed-loop feedback systems that sample energy output in real-time. If the pulse energy drifts, the power supply adjusts the pump voltage to maintain consistent clinical output, ensuring patient safety.
A multi-wavelength system allows clinics to address a wider range of indications. The 1064nm wavelength is ideal for treating deep dermal pigments and dark inks in darker skin types. The 532nm wavelength targets superficial epidermal lesions and warm-toned tattoo inks. Fractional handpieces generate micro-zones of optical breakdown (LIOBs) in the epidermis to stimulate collagen synthesis for skin rejuvenation.
Our integrated R&D facility manages the entire production cycle, from semiconductor wafer dicing and laser chip encapsulation to finalized clinical workstations. This structural integration ensures consistent quality control and rapid updates to device designs based on market feedback.
Every laser stack, diode module, and complete machine undergoes rigorous testing procedures, including thermal stress profiling, spectral output verification, and continuous pulse cycle runs prior to international shipment.
We provide full customization options for international distributors, including specialized casing designs, custom user interface software, specific wavelength configurations, and tailored optical accessories to match local market requirements.
Our manufacturing facility operates under strict medical device quality standards, ensuring our products comply with international import regulations and safety requirements.
The picosecond laser industry is shifting toward smart, multi-wavelength, and highly integrated systems. As a key Chinese manufacturing hub, Xi'an Prima focuses its development roadmap on three main technological areas:
Future systems will prioritize the integration of secondary wavelengths (like 755nm Alexandrite-like profiles and green/red dye converters) within a single compact laser engine. This will allow practitioners to target multi-colored tattoo pigments and vascular lesions without needing separate, dedicated platforms.
By incorporating real-time sensors into the handpiece and internal beam splitter, upcoming machines will continuously adjust energy outputs based on real-time skin impedance readings. This feature helps prevent over-treatment and ensures consistent energy delivery during long clinical sessions.
Leveraging our background in laser chip packaging, we are developing smaller, high-peak-power diode laser stacks. These modules are designed to simplify handpiece repair and reduce maintenance downtime for clinics worldwide.
