Advantages of Green Laser Miniaturization:

Miniaturization means physically smaller devices, reducing space occupation and making equipment more portable, thus saving valuable space. This is particularly important for various devices as it allows for greater portability and ease of movement, which is crucial in many applications. The advantages include:

  • Smaller Packaging Forms: Miniaturized laser packaging technology typically results in smaller packaging compared to TO packaging technology, eliminating the need for intermediate heat sink assembly, which is beneficial for applications requiring compact designs. Miniaturized lasers are simple, efficient, stable, compact, and easy to integrate, especially suitable for high-density and high-brightness applications.
  • Improved Electro-optical Efficiency: Electro-optical efficiency is a key indicator of laser performance, reflecting the efficiency of converting electrical energy into light energy. Miniaturized green semiconductor fiber-coupled lasers have a significant advantage in electro-optical efficiency (with small batch verification, an increase of 1%-2% over the original efficiency). High-efficiency lasers not only reduce energy consumption but also mean longer life and higher stability.
  • Enhanced Heat Dissipation Performance: Miniaturized green semiconductor fiber-coupled lasers can effectively reduce thermal resistance, thereby improving heat dissipation. Excellent heat dissipation prevents overheating and maintains stable operation. Compared to traditional lasers, the heat dissipation performance of miniaturized green semiconductor lasers has significantly improved, benefiting the stability and environmental adaptability of the devices.
  • Homogenization Performance: On top of the aforementioned improvements, miniaturized green lasers still achieve a homogeneity of over 90%.
