Protective Windows for High Energy Lasers

Product Overview:

Protective windows for high-energy lasers are designed to safeguard expensive optics inside the laser cutting head. They shield optical components like focusing lenses from splatter and debris during laser processing. These windows are made of high purity fused silica and are suited for usage under power rates exceeding several kW2. They have excellent optical performance and UV resistance.

Features:

• High light transmittance: It has a high light transmittance for laser wavelengths. For example, at a wavelength of 1064nm, the transmittance can reach over 99.7%, ensuring the effective transmission of laser energy.

• Anti-reflective coating: The surface is coated with high-quality anti-reflective coating, which can reduce the reflection and scattering of laser on the window surface, improve the laser transmission efficiency, and prevent the back reflection of the laser beam from causing interference to the laser system.

• Low wavefront distortion: After ultra-smooth polishing treatment, the surface has high flatness, which can ensure the minimum wavefront distortion when the laser beam passes through.

Applications:

1. Industrial manufacturing

• Laser cutting: In laser cutting equipment, a protective window is installed at the front end of the cutting head to protect the expensive optical components such as the focusing lens inside from damage caused by splashes, smoke and debris generated during the cutting process. These protective Windows can withstand long-term exposure to high-energy lasers, ensuring the continuity and reliability of the laser cutting process.

• Laser welding: In the laser welding system, the protective window also plays a crucial role. It can prevent the high-temperature molten material and spatter generated during the welding process from damaging the internal optical components, thereby ensuring the welding quality and the stable operation of the equipment.

2. Medical field

• Laser surgery: In the medical field, high-energy laser protection Windows are used in laser surgery equipment to ensure that the laser beam can be safely and accurately transmitted during the operation. These protective Windows can effectively block tissue debris and blood splashes generated during the operation, protect the optical components inside the equipment, and at the same time ensure the stability and accuracy of the laser beam.

• Laser beauty: In laser beauty equipment, protective Windows can prevent skin tissue fragments and liquid splashes generated during laser treatment from contaminating and damaging the equipment.

3. Scientific research laboratory

• High-energy laser experiment: In scientific research laboratories, high-energy laser protection Windows are used to safeguard the safety of experimental equipment and researchers. These protective Windows can withstand the radiation of high-energy lasers, prevent laser beams from damaging the optical components inside the experimental equipment, and at the same time provide researchers with a safe experimental environment.

4. Military and aerospace

• High-energy laser weapon systems: In the military field, high-energy laser protection Windows are used in laser weapon systems to safeguard laser emission devices and optical systems from the influence of the external environment. For instance, the protective window made of transparent magnesium-aluminate spinel ceramic can withstand the impact of high-speed raindrops and sand particles while ensuring the transmission efficiency of the laser beam.

• Aerospace sensor protection: In the aerospace field, high-energy laser protection Windows are used to protect optical sensors on board or satellites. These protective Windows can withstand extreme environmental conditions, such as aerodynamic heating during high-speed flight and micrometeoroid impacts in the space environment.

5. Other applications

• Laser marking: In laser marking equipment, protective Windows can prevent metal fragments and smoke generated during the marking process from damaging the internal optical components.

• Laser cleaning: In laser cleaning applications, protective Windows can protect the equipment from contamination by dust and debris generated during the cleaning process.

• The application scope of high-energy laser protection Windows is very wide. Their main function is to protect the key optical components in the laser system, ensuring the stable operation of the laser equipment and the safety of the operators.
