The polytetrafluoroethylene (PTFE) laser pump cavity is a key component in modern laser technology, playing a crucial role in the operation of laser systems. With its unique material properties, PTFE provides an excellent foundation for the design and functionality of the pump cavity, ensuring efficient and stable laser performance.

It is widely used across various laser applications. In industrial manufacturing—such as laser cutting, welding, and drilling—lasers equipped with this type of pump cavity can deliver high power and superior beam quality, improving processing efficiency and precision. In the medical field, PTFE pump cavities are integrated into laser surgery systems and photodynamic therapy devices, where their stability ensures safe and effective operation. Moreover, in scientific research areas such as optical studies and material analysis, the PTFE laser pump cavity provides reliable conditions for high-precision laser experiments.

Material Characteristics：
· High Reflectivity：The modified PTFE suspension resin features a high reflectivity of over 98%, excellent diffuse reflection characteristics, and outstanding spectral stability. As a result, the cavity achieves optimal coupling efficiency for superior laser output.
· Low Scattering：PTFE exhibits very low scattering properties. In a pump cavity, this means the pump light can propagate without significant energy loss or directional instability caused by scattering, ensuring higher efficiency and beam quality.
· Excellent Optical Stability：PTFE has outstanding resistance to weathering, radiation, and ultraviolet exposure. It is non-hygroscopic, non-flammable, and chemically inert to oxygen and UV radiation, ensuring long-term optical stability and durability
· Diffuse Reflection Characteristics：The PTFE pump cavity operates primarily on diffuse reflection. The pump light undergoes multiple reflections inside the cavity, providing uniform illumination on the laser medium. This uniform excitation helps enhance laser output stability and achieve even energy distribution within the beam, effectively avoiding output fluctuations and beam quality degradation caused by uneven pumping.

Applications：

· Laser Cutting：Suitable for high-power laser systems used in precision cutting of metals, gemstones, and other hard materials.

· Laser Treatment：Used in medical laser devices such as dermatological treatment systems, cosmetic laser instruments, and ophthalmic laser surgery equipment for vision correction

· Physics Experiments：Serves as a key component in laser and quantum physics experiments, providing a stable, high-energy light source for advanced research applications.

· Material Research：Enables precise control of laser energy and pulse width, offering accurate experimental conditions for studying material microstructures and performance variations.

· Excellent Pump Uniformity：PTFE pump cavities can be manufactured in various shapes and sizes to achieve uniform reflection and scattering of pump light. This ensures consistent illumination of the laser gain medium, enhancing laser output uniformity and stability while minimizing spot energy fluctuation and beam distortion

· Cost Efficiency：PTFE is readily available and more cost-effective compared to traditional high-reflectivity materials such as gold, silver, or magnesium oxide. This helps reduce overall laser system manufacturing costs and improves market competitiveness.

· High Design Flexibility：The PTFE cavity can be customized in shape, size, and reflectivity distribution according to specific laser design requirements. It can be fabricated into various geometries such as circular, elliptical, oval, or intersecting-round cross sections to meet diverse laser output needs across different applications.
