"We chose the most reliable PM type available, PANDA-PM, for our optical pulser. Users need signal stability, a trademark in the Berkeley Nucleonics product line", comments Mark Slattery, Application Engineer.
There are a variety of PM types available, each having their own properties. (See diagram) Because fibers are never perfectly symmetric, a PM-style device minimizes the modal birefringence which occurs in typical single-mode fibers. The technique incorporates boron-doped stress regions (or 'stress rods') in regions on either side of the fiber core.
The new line of BNC Light Pulse Generators provide up to 200 mW of controlled optical power, with pulse widths as low as 5 nS and adjustable amplitudes in 2 mW steps. The PANDA style PM fiber used in the pulse generators ensure outputs with highly quantifiable, repeatable properties. The family of optical pulse generators meets FDA regulations on laser safety and laser marketing protocols. The company also offers custom light pulse generator development for users needing unusual optical signal sources. For details, see http://www.berkeleynucleonics.com or call 800-234-7858.
