FIBER OPTIC Depolarizer
- PolaZero™

Product Summary
Capable of depolarizing lasers with coherence lengths of several kilometers,
General Photonics' passive depolarizer is miles ahead of the competition!
This patent pending device surprisingly comes in a small package
(85 × 60 × 10 mm for lasers with coherence lengths up to 10 meters).
Devices for longer coherence lengths (up to several kilometers) can be custom made
with minimum charges. The device is ideal for eliminating the effects
of PDL or polarization sensitivity of optical components and instruments.
Equally important, it can be used for depolarizing pump lasers to
eliminate the polarization sensitivity of Raman amplifiers. The rugged
package provides high performance and superb environmental stability.
