Prism Polarizer

Serie TFPK broadband has been developped to satisfy requirements for very high power, short pluse lasers.

TFPK - Broadband Low Dispersion Beamsplitters

These polarizers are the best choice when both high laser damage threshlod and a 90 degree reflection angle are necessary.

Main specifications :

• Input angle 45deg so beams are separated by 90deg like a cube polarizer
• Lower TWD than a cube: < l/8 gtd, l/10 typical
• High laser damage threshold > 10J/cm2 (tested to 25.8J)
• Larger CA than Brewster angle polarizers (because of angle, 45 is < 56)
• Transmission efficiency Tp > 97%; Ext ratio Tp/Ts > 500:1
• No angle tuning required!

CVI

Thin Film Plate Polarizer, 45°

Serie TFP: Thin film plate are the best choice when maximum damage resistance is necessary.

TFP polarizers are used for fluence greater than 500mJ/cm², where calcite air-spaced cannot be used.
Two typical applications are: Q-swicth hold-off polarizer and in conjonction with half waveplate as an extracavity attenuator for Nd:YAG laser fundamental and its harmonics
