Designed for demanding high-energy laser applications, the Thin Film Polarizer (TFP) is a superior alternative to traditional polarizing components. By separating s- and p-polarization components, it ensures precise polarization management crucial for optimal laser performance.

Key Features:

  • Linear Polarization: Provides exceptional linear polarization of laser radiation.
  • High Transmission: Achieves Rs/Tp:>99.8/95.0% for standard TFPs or Rs/Tp:>99.8/98.0% for high-transmittance variants.
  • Damage Threshold: Withstands high-energy environments, boasting a remarkable damage threshold of up to 10 J/cm².
  • Extinction Ratio: Offers high extinction ratios of 1000:1 and 500:1 for superior performance.
  • Wide Temperature Range: Functions reliably in temperatures ranging from -40? to +60?.


  • Intracavity Q-Switch Hold-Off Polarizer: Essential for maintaining precise Q-switching within laser cavities.
  • Extracavity Attenuator for Nd:YAG Lasers: Enables efficient laser power attenuation outside the laser cavity.
