Technical Advantages of Our Laser Diodes

01 Material Selection

We use military-grade CuW and specially formulated AuSn solder, along with imported laser chips, to ensure the fundamental reliability of the packaging.

Excellent electrical performance of chip

The electrical performance excellence of semiconductor laser chips refers to the characteristic where these chips perform well in the electrical field. The electrical performance excellence of semiconductor laser chips is of vital importance to the performance and stability of laser devices, including the following aspects:

(1) Low resistance

The lower the resistance of the chip during operation, the less heat it generates. Working at high temperatures is more stable and the lifespan of the device is longer.

（2）Thermal stability

Heat can affect the continued operation of semiconductors. One approach is to use active cooling to handle the heat. If the heat is not dealt with promptly, it will cause thermal accumulation in the area where the laser chip generates heat, accelerating the disintegration of the chip material due to high temperature. Generally, the feedback indicates that the power of the chip decays too quickly and the chip burns out. Therefore, the ability of the chip material to withstand high temperatures is a very important indicator. We often call it the “electrothermal stability” of the chip, and the highest junction temperature X is used as the constant parameter for the characterization.

02 Eutectic Bonding

Key interfaces are joined using defect-free metal and non-metal hard solder bonding processes to prevent creep. Combined with soft solder, this approach eliminates stress and ensures long-term stability of the laser.

The excellence of the welding technology framework

（1） Integration of Welding Joints & Reduced Resistance:

① By merging 50% of the welding joints between units, the electrical resistance during operation is effectively reduced (Q=I²Rt). This lowers resistance and minimizes heat generation at the welded connections.

② Optimized Thermal Conduction via Structural Design: The consolidated welding structure enables heat from the Bar to transfer according to the material’s thermal conductivity. By eliminating traditional thermal resistance interfaces, heat from the chip is dissipated more rapidly.

③ Thermal Conductive Ceramic Isolation & Stress Control: The segmented design of the thermal conductive ceramic ensures that packaging stress from the ceramic intelligently affects only the WCu electrode, preventing any impact on the chip. This guarantees the chip remains unaffected by ceramic- induced mechanical stress.

（2） Welding Stress Management

Stress management is a critical guarantee for the long-term stability and reliability of the module.

03 Thermal Management

Guided by thermal simulation software and validated through extensive experimental data, we have developed an optimized thermal dissipation model that enables high power density laser chips to be packaged within a compact footprint.

Advantages of Water-Cooled Heat Sinks

Based on the results of the Finite Element Analysis (FEA) model, the chip’s operating temperature demonstrates excellent thermal performance.

04 Optical Shaping

Customized beam shaping is available to meet client requirements, offering excellent energy transmission and superior homogenization performance.

Cylindrical Lens Beam Shaping

Using cylindrical lenses to achieve fast-axis collimation of semiconductor lasers, effectively reducing the divergence angle of the emitted beam.

05 Performance Testing

We apply stricter-than-standard testing conditions to push the limits of diode packaging. This results in narrower FWHM (Full Width at Half Maximum) and higher power output.
