Product details
Overview
Seed oscillators in ultrafast fiber lasers need isolation that leaves polarization untouched, and the FT-1064-66 is built for that slot. Its terbium gallium garnet (TGG) stage rotates the 1064 nm forward beam while dumping reverse light, up to the 300 mW continuous rating, so feedback cannot re-enter the cavity and corrupt mode-locking. The PM path holds polarization from input to output instead of accepting arbitrary states, which matters wherever downstream amplifiers, modulators or frequency doublers are polarization-sensitive. Ordering options cover both-axis and fast-axis-blocked working configurations. This compact TGG unit suits seed protection, sensor interrogation and instrument front ends running at 1064 nm.
Key Features
- TGG-based polarization-maintaining isolator at 1064 nm
- Rated for 300 mW continuous optical power
- Maintains polarization state end to end for polarization-sensitive systems
- Faraday rotation attenuates back reflections to protect the source
- High isolation with low insertion loss, high extinction ratio and high return loss
- Stable and reliable operation for demanding laser environments
Applications
- Ultra-fast fiber laser systems
- Test instruments
- Fiber sensor systems
- Fiber laser sources
