General Description
The free space isolators offered by Photonics of Crystals (POC) are engineered to ensure exceptional performance in optical systems by minimizing back reflections and reverse transmitted beams. These isolators are available in two categories: polarization-dependent and polarization-independent.
Polarization-dependent isolators feature three core components: an input polarizer, a Faraday rotator, and an output polarizer. Together, these components provide effective isolation, ensuring laser polarization stability.
Polarization-independent isolators integrate birefringent crystals, a Faraday rotator, and half-wave plates, making them suitable for maintaining optical system stability, especially in fiber laser systems.
POC uses high-quality magneto-optic crystals with superior Verdet constants, low absorption coefficients, and advanced polarizer coatings to achieve outstanding extinction ratios and low transmission losses. With customization capabilities, POC ensures that each isolator meets specific operational demands, ranging from ultrafast laser systems to precision laser machining.
Applications
- Laser Precision Machining
Free space isolators enhance laser machining processes by preventing destabilizing back reflections, ensuring cleaner cuts and more accurate material processing. - Laser Sensing Systems
These isolators support high-precision sensing by maintaining the integrity of the transmitted signal, ensuring enhanced sensitivity and reliability. - Ultrafast Laser Systems
Designed to handle high-power ultrafast laser pulses, these isolators minimize interference, enabling stable operation in demanding applications.
