High-precision semiconductor laser stacks engineered for clinical-grade tattoo removal platforms and high-fluence hair removal systems.
Understanding how high-power diode stacks and solid-state optical configurations define clinical efficacy in dermal pigment disruption and hair removal.
Modern tattoo removal platforms rely on rapid energy transfer. Our laser technology transitions from photothermal targeting (used in hair removal) to intense photomechanical acoustic shockwaves. This process shatters deep-lying tattoo ink pigments into microscopic particles without transferring thermal energy to surrounding epidermal layers.
Tattoo pigments respond selectively to specific wavelengths. By manufacturing multi-wavelength vertical diode modules (spanning 755nm for green/blue ink, 808nm for universal chromophore absorption, and 1064nm for deep black and dark ink), our equipment covers the full clinical spectrum, providing complete clearance profiles for diverse skin phototypes.
Stability under continuous duty cycles is the primary challenge in medical-grade lasers. Utilizing AuSn (Gold-Tin) hard solder technology and Micro-Channel Cooler structures, our stacks handle high thermal loads. This cooling structure prevents thermal degradation of the optical bar arrays, extending stack life to over 40 million shots.
Prevents solder migration under high pulse frequencies, ensuring stable peak power outputs without wavelength shifting.
Dual cooling mechanisms keep the internal diode junction temperatures below 35°C during continuous heavy clinical usage.
Optimized semiconductor architecture transforms input current into coherent light energy with minimal waste heat production.

Prima Beauty Laser is known for providing a wide range of high-quality beauty equipment, such as Diode hair removal laser machine, CO2 fractional laser machine, Pico laser machine, IPL laser machine, Skin management machine, etc. With more than 10 years of aesthetic and laser experience, its head office integrates the research and development of diode lasers and solid-state lasers, including the production and manufacturer of beauty equipment sales.
We provide end-to-end solutions: ongoing professional training, reliable technical support, responsive after-sales service, and efficient client management assistance.
As a Chinese mid-to-high-end beauty equipment supplier, we prioritize customer satisfaction and offer excellent after-sales support. Our dedication to innovation and excellence has enabled us to integrate the research and development of laser chips, production, manufacturing, and sales of beauty equipment under one roof. This ensures that our customers receive the latest advancements in beauty technology, backed by our expertise and industry-leading support.
Our commitment to quality is unwavering. Every device undergoes rigorous testing to ensure it meets our high standards before it reaches your hands. We also support the customization of OEM or ODM. Whether it's beauty equipment or laser chips, we can customize it to fit your needs. We are always a step ahead in developing new and improved beauty equipment that caters to evolving market demands.
In addition to our extensive product range, we also provide OEM/ODM services, allowing our clients to customize and brand our beauty equipment to meet their specific requirements. Whether you are looking to enhance your beauty salon or medical beauty hospital with state-of-the-art equipment, we have the solutions to elevate your business and exceed your clients’ expectations.
Leveraging industrial clusters, advanced photolithography packing systems, and optimized manufacturing logistics to deliver quality at scale.
By conducting epitaxy, wafer dicing, package soldering, and final device assembly within our vertically integrated factory cluster in Xi'an, we eliminate middle-man markups and reduce supply-chain risk. Our turnaround time for custom diode stack handle repair or OEM fabrication is up to 40% faster than European counterparts.
Laser diode array mounting requires extreme cleanroom standards. Our automated eutectic die-bonding systems operate in Class 10,000 and Class 100 localized cleanrooms to ensure that particulates do not compromise the optical facet coatings of high-power emitters.
Before shipment, every customized laser diode stack is subjected to continuous cyclic burn-in tests of 10,000+ pulses. This processes reveals infant mortality failures in semiconductor crystals prior to shipping, keeping field-failure rates under 0.1% globally.
Compliance with international medical device rules ensures global product security, smooth import clearance, and liability protection.
Providing clear, technical insights to help global procurement teams make informed purchasing decisions.
High-power diode stacks function as either direct light sources (e.g., in hair removal handles using 755nm/808nm/1064nm wavelengths) or as high-energy optical pump sources for solid-state Nd:YAG crystals in Q-switched laser tattoo removal platforms. The diode stack delivers the high-intensity optical excitation necessary for the solid-state medium to reach population inversion, producing nanosecond or picosecond tattoo-disrupting pulses.
Gold-Tin hard solder has a high melting point (280°C) and strong resistance to thermal creep under cyclic stresses. In contrast, indium solder is soft and prone to oxidation and electro-thermal migration (which causes the solder to flow under load). AuSn bonding ensures that the diode bars stay aligned and maintain solid electrical contact, preventing premature facet breakdown.
We specialize in both Micro-Channel Cooling (MCC) and Macro-Channel Cooling. MCC features microscopic water channels directly below the semiconductor junction, allowing heat dissipation of up to several hundred watts per square centimeter. This requires deionized water. Macro-Channel Cooling features larger channels, allowing the use of standard purified water, simplifying system maintenance for clinic operators.
Yes, we provide custom OEM/ODM handle refurbishment. We can replace worn-out diode stacks from international brands with customized power ratings (from 300W up to 4800W) and custom wavelength configurations (755nm, 808nm, 940nm, 1064nm) matching the original dimensions of the target applicator handle.
Standard OEM/ODM orders are manufactured, run through our rigorous burn-in test protocols, packaged, and shipped within 10 to 15 business days. Refurbishment or handle repairs usually take 5 to 7 days from the time we receive the original components at our Xi'an facility.
High-power modular laser components built to medical standards, optimized for integration into complete tattoo removal and aesthetic skin platforms.
