15000W Water Cooled QCW Diode Side-pumped Module

Product Introduction of 15000W Water-Cooled QCW Diode Side-Pump Module
The 15000W water-cooled QCW diode side-pump module is a high-power laser pump product developed by Beijing Real-Light Technology Co., Ltd. Taking the self-developed WA series water-cooled diode laser linear arrays as core components, it realizes high peak power pumping and high-gain laser output while effectively suppressing Amplified Spontaneous Emission (ASE). With superior beam quality, compact structure and low thermal effect, it serves as a mainstream matched pump source for solid-state laser manufacturing and is widely applied in industrial processing, biomedicine, scientific research and other industries.

Core Product Advantages and Features
Optimized for electro-optical conversion efficiency, pumping uniformity and operational stability, this module delivers excellent overall performance and is suitable for long-duration, heavy-duty industrial and laboratory working conditions:
1.High electro-optical conversion efficiency
Benefiting from mature laser array packaging and optical path design, the module features high energy utilization efficiency. It maintains outstanding electro-optical conversion performance under high-power operation, effectively reducing energy consumption and improving the cost efficiency of the entire laser system.
2.Uniform pump absorption
Standardized array layout combined with precise optical design delivers evenly distributed laser output, which enables Nd:YAG laser crystals to absorb pump light sufficiently and uniformly. This fundamentally guarantees the output stability and beam quality of the complete laser equipment.
3.Stable and reliable operation
Equipped with a professional high-efficiency water cooling system, it greatly reduces heat accumulation during operation and mitigates performance degradation caused by thermal deformation. The module runs stably in QCW wave mode with a low failure rate, capable of supporting long-term continuous operation.
4.Compact structure for easy integration
Its streamlined and optimized internal layout achieves a compact overall size compatible with various standard solid-state laser structures. It simplifies equipment integration, assembly and subsequent maintenance, and meets the requirements of mass production and diversified equipment renovation.
