Ultrafast Laser Brewster's Angle Dispersing Prisms

Product catalog summary

Overview: The document provides technical specifications and usage guidelines for Ultrafast Laser Brewster’s Angle Dispersing Prisms, which are used for dispersion compensation in laser systems.

Specifications:

Materials: UV grade fused silica, LaKL21, and SF10 or N-SF10, all with an index of 3/3 and striae grade A.
Usable Wavelength Range: UV fused silica: 185–2100 nm; LaKL21 and SF10: 370–2000 nm.
Surface Flatness: ≤λ/10 at 632.8 nm over the clear aperture.
Clear Aperture: ≥90% of face.
Surface Quality: 40-20 scratch-dig.
Apex Angle: UV fused silica: 69.06° ±0.25°; LaKL21: 63.00° ±0.25°; SF10: 60.60° ±0.25°.
Dimensions Tolerance: +0/-0.25 mm.
Chamfers: 0.5 mm face width x 45° maximum.
Cleaning: Non-abrasive method using acetone or isopropyl alcohol on lens tissue is recommended.

Applications: These prisms are used intracavity for compensating dispersion of fixed cavity optics or externally for manipulating pulse characteristics in laser systems.

Graphical Data: The document includes graphs showing the calculated Group Velocity Dispersion (GVD) and Cubic Term for UV Fused Silica, LaKL21, and SF10 materials across various wavelengths.

Ordering Information: Models are available in two sizes (15 mm and 25 mm) for each material type, with specific model numbers provided for ordering.

Additional Resources: For further guidance on prism selection and setup, refer to Newport Application Note #29, "Prism Compressor for Ultrashort Laser Pulses," available on the Newport website.
