Industrial-strength vertical diode stacks and optoelectronic modules engineered for OEM/ODM integrations and direct handle repairs.
The global aesthetic market is undergoing a rapid transition toward high-fluence, non-invasive systems. At the core of this transition are OPT (Optimal Pulse Technology) and SHR (Super Hair Removal) systems. Unlike traditional IPL units that deliver erratic energy spikes causing epidermal damage, OPT utilizes square-wave pulse control. This technology maintains uniform pulse profiles, delivering consistent energy density (fluence) throughout each pulse's duration.
By pairing OPT with SHR's in-motion technique—which sweeps the treatment area while firing low-fluence pulses at high repetition rates (up to 10Hz)—modern clinical systems heat the target hair follicles incrementally. This drastically reduces thermal damage to surrounding tissue, making treatment safer for a broader spectrum of skin types (Fitzpatrick scale I-VI).
For medical spa operators, aesthetics equipment distributors, and device manufacturers, selecting components backed by strict compliance certifications (such as CE Certification) is no longer optional. Compliance acts as the ultimate gatekeeper for market access, professional accountability, and risk mitigation.
Xi'an Prima Beauty Equipment Co., Ltd. leads the integration of advanced semiconductor packaging with aesthetic medical technology. By controlling the supply chain from the packaging of vertical diode bars to final cosmetic platforms, we deliver unparalleled structural and performance advantages.
Our cleanrooms package raw GaAs (Gallium Arsenide) bars into vertical configurations. By soldering bars using gold-tin (AuSn) alloys rather than indium, we prevent solder migration and oxidation, significantly boosting stack lifetime even under high repetition duty cycles.
Micro-channel coolers (MCC) feature engineered copper channels measuring only micrometers across. This allows cooling water to flow directly beneath the laser chips, reducing thermal resistance to <0.4 K/W and preventing thermal wavelength drift during back-to-back SHR sessions.
Fast Axis Collimator (FAC) micro-lenses are aligned to each laser bar with sub-micron accuracy. By collimating the high-divergence fast axis of the diode emission, optical transmission efficiency is increased to >90%, yielding tighter beam profiles and deeper subcutaneous penetration depths.
Welcome to Xi’an Prima Beauty Equipment Co., Ltd., your trusted partner in high-quality beauty and medical laser platforms. With over 10 years of experience, we specialize in the research, development, and vertical manufacturing of cutting-edge aesthetic technologies.
Our head office integrates the entire industrial vertical pipeline: from high-power diode laser semiconductor chips to raw optoelectronic module assembly and final beauty system fabrication. Our extensive product portfolio includes Diode Hair Removal Laser Systems, CO2 Fractional Laser Systems, Picosecond Lasers, and advanced IPL/SHR platforms.
Operating as a mid-to-high-end global supplier, we emphasize performance, clinical safety, and absolute reliability. Our engineering teams offer custom OEM/ODM solutions, manufacturing tailor-made laser diode stacks and control boards to meet the specifications of worldwide medical spa networks and repair service centers.
We combine diode chip packaging, FAC optics, and specialized driving circuits under one roof. Our engineers rapidly iterate designs to incorporate the newest clinical trends, such as triple-wavelength (755nm + 808nm + 1064nm) arrays and high-power density stacks.
Every laser stack undergoes detailed stress tests, including 48-hour continuous burn-in, electro-optical conversion efficiency profiling, and beam profiling analysis. Only certified components pass through to our final shipping lines.
From custom shell designs to proprietary software interfaces and specialized water cooling loops, we offer complete private-label support. This helps medical distributors establish market differentiation with unique cosmetic laser platforms.
Our systems comply with European medical equipment standards. These certificates ensure smooth customs clearance and clinical safety authorization across global jurisdictions.
Depending on geographical and target demographic factors, aesthetic laser needs vary. Understanding these requirements helps suppliers adjust optical configurations to ensure consistent treatment outcomes.
Demographic Focus: Broad Fitzpatrick spectrum (I-VI) with high demand for dual and triple-wavelength configurations (755nm + 808nm + 1064nm).
Technical Demand: High peak power (1200W - 2400W) with micro-channel cooling to sustain heavy daily patient volumes in large medical spas.
Demographic Focus: Predominantly Fitzpatrick IV-VI skin types requiring safer melanin-absorption curves.
Technical Demand: 1064nm Neodymium-doped yttrium aluminum garnet (Nd:YAG) wavelength integrations combined with long pulse durations (up to 400ms) to bypass superficial epidermis risk and deliver thermal energy directly to the dermal papilla.
Demographic Focus: Fitzpatrick III-IV skin types with dark, coarse hair follicles.
Technical Demand: 755nm (Alexandrite-equivalent) and 808nm diode stacks paired with sapphire contact cooling plates that maintain surface temperatures at 0°C to 4°C, preventing hyperpigmentation.
To achieve selective photothermolysis, the laser energy must target the chromophore (melanin) without causing damage to hemoglobin or water. The 755nm wavelength offers high melanin absorption, ideal for fair skin and fine hair. The standard 808nm wavelength balancing penetration depth and melanin absorption. The 1064nm wavelength features lower melanin absorption but deep penetration, bypassing epidermal melanin to safely treat darker skin types.
Essential technical information for optical engineers, clinical distributors, and medical equipment technicians.
OPT represents an evolution of Intense Pulsed Light (IPL). Traditional IPL devices deliver energy in decaying spikes, leading to excessive heat on the skin surface and increased risk of burns. OPT utilizes advanced control electronics to deliver square-wave pulses, maintaining stable energy output throughout each pulse's duration. This ensures safer, more consistent clinical results and allows for faster treatment speeds (SHR mode).
CE Certification indicates that the device complies with European medical safety, health, and environmental protection standards. For distributors and spa operators, this ensures the equipment meets strict mechanical, electrical, and radiation safety limits (such as electromagnetic compatibility and optical safety). Using certified equipment helps mitigate legal liabilities and ensures patient safety.
Micro-Channel Coolers (MCC) feature microscopic water channels directly underneath the semiconductor diode bars. This design increases the heat-dissipating surface area, maintaining the diode junction temperature at optimal levels. As a result, MCC stacks can achieve high peak power outputs (up to 4800W) and support lifespans exceeding 50 million pulses. Macro-Channel Coolers, while more cost-effective, feature larger channels and lower heat-exchange efficiency, limiting peak power capabilities.
Integrating three wavelengths allows a single applicator to target different hair follicle structures simultaneously. The 755nm wavelength targets superficial hair bulge melanin (ideal for light skin and fine hair). The 808nm wavelength targets deep follicle structures. The 1064nm wavelength penetrates deepest to target the hair bulb and papilla, making it safe for dark-skinned patients (Fitzpatrick VI).
Yes, we specialize in OEM/ODM diode stacks for handle repair services worldwide. We can customize the dimensions of copper heatsinks, the number of laser bars (typically 5 to 20 bars), and target power outputs (ranging from 300W to over 3500W) to match the specifications of your existing handpieces.
