This patented device comes in a surprisingly small package (85 × 60 × 10 mm) for lasers with coherence lengths less than 10 meters. Devices for coherence lengths in the kilometer range can be custom made. This 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. Specifications: Center Operating Wavelength1 1310 nm, 1550 nm Operating Wavelength Range ± 50 nm Coherence Length of Light Source 10 m standard, others specify Output Degree of Polarization < 5% Insertion Loss 1.0 dB typical, 1.4 dB max.
