Product innovation

• High-power laser chip technology breakthrough: Based on the breakthrough of the key technology of 66W high-power laser chip, the module adopts a single tube arrangement and combination of 36 66W chips, combined with efficient optical design and precise process control, which reduces the loss and scattering of light, improves the transmission efficiency of light, and integrates the red light chip into the module, successfully realizing the commercialization of the 1700W single-pump module.
• Near-junction cooling design: The module design adopts the method of near-junction cooling, which greatly reduces the thermal resistance of the chip heat conduction, and through the rapid heat exchange of the heat dissipation medium, the chip efficiently dissipates heat, reduces the chip junction temperature, and ensures reliable operation at 65A current.
• Lightweight shell packaging process: The shell is made of aluminum-based lightweight materials, the optical path layout is compact, the module weight ≤ 1110g, and the appearance size: 120mm*163.5mm*33.5mm, which is 40% less than the traditional copper-based solution to meet the needs of customers for lightweight and miniaturization.
