OEM Fused Silica Prisms (Right Angle, Penta, Wedge) for High-Power Laser Beam Steering

OEM Fused Silica Prisms (Right Angle, Penta, Wedge) for High-Power Laser Beam Steering

1. Core Material & Component Types:

• Material: Premium Synthetic Fused Silica (Quartz). An ultra-pure, amorphous glass with exceptional optical and thermal properties.

• Prism Types: Includes three key geometries for beam manipulation:

  • Right-Angle Prism: For 90-degree beam bending or used as a reflector.

  • Penta Prism: Deviates a beam by exactly 90 degrees regardless of minor orientation errors.

  • Wedge Prism: A thin prism with a small angle for precise, small-angle beam steering or dispersion compensation.

2. Defining Physical & Optical Properties:

• Ultra-High Laser Damage Threshold (LDT): Fused silica's primary property, making it essential for high-power and ultrafast pulsed laser systems where other materials fail.

• Exceptional Thermal & Chemical Stability: Low thermal expansion and high resistance to thermal shock and chemical corrosion ensure stable performance under intense laser irradiation.

• Broad Spectral Transmission: Excellent transmission from deep UV (~185 nm) to near-infrared, suitable for a wide range of laser wavelengths.

• High Homogeneity & Low Inclusions: Minimizes wavefront distortion, scatter, and internal energy absorption that could damage the optic.

3. Primary Functions in a Laser System:

• Beam Steering & Deflection: The core function. Precisely redirects (steers) a laser beam's path by a defined angle (e.g., 90° via a right-angle or penta prism).

• Beam Displacement & Alignment: Wedge prisms are used in pairs for fine, adjustable lateral beam shifting without changing the beam direction.

• Retroreflection & Image Flipping: Right-angle prisms can invert or revert an image while reflecting light.

• Polarization Maintenance: Certain prism configurations and coatings can preserve the polarization state of the laser beam.

4. Target Applications & Industries:

• Industrial Laser Processing: Beam delivery in high-power cutting, welding, and marking systems.

• Scientific & Research Lasers: In complex setups for spectroscopy, particle accelerators, and ultrafast laser laboratories.

• Medical Laser Systems: For beam guidance in surgical and aesthetic laser equipment.

• Defense & Aerospace: Laser rangefinders, target designators, and directed energy systems.

• Metrology & Interferometry: As stable reference reflectors or beam directors in precision measurement instruments.
