Explore our industrial-grade laser stack components, built using micro-channel cooler technologies to guarantee maximum lifetime and compatibility for handle repair and equipment builds.
Driven by evolving technologies and safety-centric customer preferences, the global aesthetic device market is witnessing a major transformation toward modular components, higher peak power, and multithread wavelengths.
The standard 808nm wavelength is now coupled with 755nm (Alexandrite target) and 1064nm (Nd:YAG target) into a single diode laser stack. This multi-wavelength strategy enables clinics to treat all Fitzpatrick skin types (I-VI) safely and effectively within a single session.
Clinical efficacy is shifting toward higher output powers (from 1200W up to 4800W) to enable short pulse widths down to 10-30ms. This prevents thermal accumulation in surrounding tissues while delivering lethal doses of energy directly to the hair follicles.
Traditional macro-channel cooling (MCM) is being rapidly replaced by high-precision Micro-Channel Coolers. MCC allows water to flow directly through internal micro-channels within milliseconds of the diode stack, reducing thermal resistance to the physical limit.

Operating from a state-of-the-art aesthetic and semiconductor fabrication cluster in China, Xi'an Prima utilizes advanced factory integration to optimize delivery times, consistency, and durability.
By bringing the research and development of laser chips, wafer packaging, stack manufacturing, handle assembly, and final testing under a single roof, we eliminate intermediate steps, reduce quality deviation, and secure direct control over every product stage.
All diode stack bar alignments and bonding operations are executed in Class 10,000 cleanrooms. This prevents dust and microscopic particles from adhering to the emitting surface of the bar facets, completely eliminating early cataclysmic optical damage (COD).
With immediate access to specialized local materials, high-purity copper heatsinks, and advanced packaging raw products in China, we sustain constant output capacity. Our facility remains insulated from macro supply shocks, keeping delivery times to within 5-10 business days globally.
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.
We remain at the absolute vanguard of aesthetic technology. By focusing on microchannel geometry optimization and low-pressure drop manifolds, we ensure our diode stacks receive uniform water flow. This prevents localized heat pockets from damaging individual laser bars.
Whether you require a custom mechanical design to replace a damaged Alma Soprano handle, a high-power diode vertical stack for an industrial application, or a customized logo screen interface, our engineering team can modify design assets quickly and reliably.
Understanding the engineering mechanics behind high-output diode stacks is essential for wholesale buyers, medical spa distributors, and device refurbishers.
Laser diodes exhibit a specific electro-optical conversion efficiency (ECE), usually around 45%-55%. The remaining energy converts directly to heat. A stack running at 2400W requires optimized micro-channel heatsinks to dissipate heat immediately, ensuring the diode remains at its ideal wavelength range.
Indium solder is prone to "indium migration" at elevated temperatures, leading to short circuits and stack failure. Xi'an Prima exclusively uses high-temperature Gold-Tin (AuSn) hard solder. AuSn withstands extreme mechanical stress and thermal fatigue, increasing the lifetime up to 50 million shots.
By mounting micro-lenses on the emitting facets of the diode stack, the highly divergent laser beams are collimated into a low-divergence parallel spot. This concentrates energy onto the target skin region, optimizing tissue penetration depth while keeping thermal scatter minimal.
Our commitment to medical safety and manufacturing consistency is supported by international testing certifications and rigorous quality assurance credentials.
From global medical laser repair shops to new high-performance aesthetic machinery assembly lines, our products serve a variety of commercial environments.
Aesthetic service providers and medical engineers use our micro-channel and macro-channel diode stacks to rebuild burned-out handpieces (e.g., Alma Soprano, LightSheer, and various Chinese brands). By swapping the stack rather than purchasing a brand-new handle, operators save up to 70% in maintenance costs.
Distributors and technology startups developing customized high-power hair removal stations rely on our vertical stacks. Our standardized designs allow engineers to plug our systems directly into high-current power supplies and micro-filtration cooling units.
Our micro-channel cooler modules are also adapted as pumping sources for solid-state laser systems, scientific research laboratories, and material processing equipment requiring stable optical energy output.

Diode laser stacks fail primarily due to thermal stress, optical contamination, and water quality issues. When hard cooling water is used, calcium buildup blocks the microchannels, resulting in immediate overheating. Additionally, using low-quality Indium solder leads to thermal migration and electrical shorting between the diode bars. Xi'an Prima solves this by utilizing AuSn hard-solder packaging and offering microchannel cooler models that minimize thermal accumulation.
Micro-Channel Cooling features a network of copper micro-channels directly beneath each laser diode bar. This layout minimizes the distance between the hot laser junction and the coolant, dramatically lowering thermal resistance. Macro-channel cooling utilizes a larger single chamber which has higher thermal resistance. While MCM is less demanding of water quality, MCC allows the system to run safely at much higher peak power settings and higher repetition rates.
Yes, we design specialized replacement diode stack structures, such as our OEM LT Laser Diode Stack for ALMA Handle Repair. These modules match the structural sizes, positioning pins, and water inlet/outlet geometries of major clinical laser brands, simplifying handle refurbishment for repair centers.
To prevent scaling and corrosion within the micro-channels (which are less than 100 micrometers wide), you must use deionized (DI) water or pure distilled water. The water resistivity should be maintained between 1 to 2 Megaohms. The system's deionization filters and particle filters must be replaced regularly to keep the channel paths clean.
Yes, we specialize in multi-wavelength stack customization. You can choose to mix 808nm, 755nm, and 1064nm bars in a single vertical stack (e.g., in a 10-bar stack, you might select 3 bars of 755nm, 4 bars of 808nm, and 3 bars of 1064nm) to target different melanin concentration levels and hair depths.
