Product Definition and Technical Importance

A high power free space isolator is a magneto-optical device designed to preferentially transmit light in a single direction, thereby protecting upstream optics from back reflections. Preventing back reflections is critical, as they can cause various instabilities in light sources, such as:

• Intensity noise
• Frequency shifts
• Mode hopping
• Loss of mode lock

Furthermore, strong back-reflected light has the potential to cause permanent damage to optical components.
