Femtoline Polarizing Optics
Femtoline polarizing optics includes round and rectangular thin film laser polarizers coated for 343 nm, 515 nm, 800 nm, 780-820 nm, 1030 nm, 1010-1050 nm wavelength. Various AR coated waveplates including zero order optically contacted or air-spaced waveplates, low order and multiple order waveplates, dual wavelength waveplates are available for fast off-the-shelf delivery. Polarizing optics also includes polarization plane rotators, group velocity delay (GVD) compensation calcite plates and variable attenuators for femtosecond linearly polarized laser pulses.

Thin Film Polarizers (Round) seperate s- and p-polarization components. They can be used as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters due to the high damage threshold reaching 100 mJ/cm2, at 800.

Thin Film Polarizers (Rectangular) seperate s- and p-polarization components. Thin Film Polarizers can be used as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters.
Zero Order Plates are comprised of two different plates cut parallel to their optical axis. This construction makes plates less dependent on temperature.
For high power applications, made of single crystal quartz, Ø17 clear aperture.
These Zero Order Dual Wavelength Plates are used for Ti:Sapphire and Yb:KGW/KYW lasers.
Laser damage threshold is >100mJ/cm2, 50 fsec pulse, 800nm typical, a ∅17mm of ∅20mm clear aperture, made of single crystal quartz.
Low Order Plates are less temperature sensitive and temperature dependent than Multiple Order Plates. These plates are suitable for high power applications.
Intended to rotate beam polarization plane strictly to an appropriate angle using the circular birefringent effect, made of crystalline quartz.
These Compensation plates, made of Calcite, are available with different orientation for different Group Velocity Delay compensation - starting from tens of femtosecond up to tens of picosecond delay compensation.
Divides laser beam into two parallel beams of manually adjustable intensity ratio, large dynamic range, negligible transmitted beam deviation, high optical damage threshold.
Divides laser beam into two beams separated by 68° of manually adjustable intensity ratio, large dynamic range, negligible transmitted beam deviation.
