WOP | Custom Waveplates

Detailed description :

Fabrication of custom waveplates is based on the inscription of self-organized nanograting’s inside fused silica glass using a femtosecond laser.

Writing nanograting allows the creation of predefined shapes of waveplates with high precision.

Custom waveplates are unique waveplates that alter the polarization state of a light wave passing it.

Space variant waveplates have the ability to control fast axis and retardance distributions simultaneously with any functions.

Custom waveplates enable tailored control of spatial polarization in any beam shape.

• Custom-shaped waveplate. Retardance λ/2@532nm, the fast axis is uniform. (refer image in gallery)
• Custom-shaped waveplate. Retardance from 0 to λ/2@532nm, the fast axis is uniform. (refer image in gallery)
• Custom-shaped waveplate. Retardance λ/4 (the inner circle) and λ/2@532nm (the outer circle), fast axes are perpendicular. (refer image in gallery)

Main features :

• Wavelength ranges from 200 nm to 3500 nm
• Retardance range from 10 nm to 2000 nm
• Any shape (rectangle, circle, triangle, custom)
• Custom retardance and fast axis profiles
• High damage threshold: 63,4 J/cm² @1064 nm, 10 ns and 2,2 J/cm² @1030 nm, 212 fs
• High 94% transmission @ 1030 nm (no AR coating)
• Aperture size from 1 mm to 15 mm
• Suitable for high LIDT applications and high-power lasers
• Reliable and resistant surface – the structure is inside the bulk
