The BB8-5I EOT (End-Output Terminated) Faraday Isolator is a high-performance component designed for use with sapphire laser systems, specifically those operating in the broadband 800nm wavelength range with a spectral bandwidth of 150/-100nm. It's an essential element for protecting sensitive optical systems from back reflection, which can lead to unwanted optical noise and instability.
The BB8-5I isolator is built using a Faraday Rotator technology, which is a proven technique for achieving effective optical isolation. It consists of a bidirectional optically pumped magnesium-neodymium-iron (MgNdFe) crystal sandwiched between two polarizers. This design ensures efficient optical isolation for CW (Continuous Wave) and pulsed lasers, with a typical isolation bandwidth of 30nm at 800nm.
This isolator is characterized by its excellent isolator insertion loss, which is typically below 0.5dB, and its low isolator output power insertion loss, which is typically below 0.3dB. Its high optical power handling capacity allows it to operate with laser powers up to 40W, making it suitable for demanding applications.
The BB8-5I Faraday Isolator also excels in its small form factor. With a compact size of 25.6mm x 34.2mm x 31.2mm, it is an ideal choice for integration into confined or space-limited systems. Furthermore, its threaded mounting makes it easy to install and secure in various optical paths.
With its exceptional isolation performance, combined with its robust design and small size, the BB8-5I EOT Faraday Isolator proves to be an indispensable tool for ensuring the stability and reliability of sapphire laser systems working in the 800nm range.
A Faraday optical isolator is an essential component in many laser systems, especially in those that utilize sapphire lasers with broadband 800nm output.
