Advantages of Miniaturization:


Compact Packaging: 

Lumispot Tech's miniaturized lasers outperform traditional TO-packaged lasers with smaller form factors and eliminate the need for intermediate heat sinks, benefiting applications that require compact designs. The streamlined and efficient structure of these lasers makes them ideal for high-density and high-brightness applications.


Enhanced Electro-Optical Efficiency:

 A key performance metric for lasers is electro-optical efficiency, which indicates the efficacy of converting electrical energy into optical energy. Lumispot Tech's miniaturized green semiconductor fiber-coupled lasers demonstrate a significant advantage in this area, with small-scale validations showing an increase of 1%-2% in efficiency. High-efficiency lasers not only reduce energy consumption but also promise longer lifespans and greater stability.


Improved Thermal Performance:

By effectively lowering thermal resistance, these miniaturized lasers enhance cooling effects, preventing overheating and maintaining a stable operating state. This improvement is crucial for the reliability and environmental adaptability of the devices.



Despite the enhancements in size, efficiency, and cooling, Lumispot Tech's miniaturized green lasers maintain a homogeneity performance above 90%, ensuring consistent quality and reliability across applications.
