Alpha-Core Intros Power Cables for Pulsed Lasers


Shelton, CT — Alpha-Core division of Bridgeport Magnetics Group, Inc. has developed a flat power cable for pulsed laser applications where high power pulses must be transmitted with extremely low impedance with- out distortion. Applications include military products such as range find- ing, targeting and radar. In addition,


The new BM Pulse Cable series


utilizes two ribbon shaped conduc- tors — each enclosed in a micro-thin, high grade polymer film, typically Polyester or Polyethylene Naphtha - lene. The film is bonded to the base metal in a proprietary process. The two conductors are laminated inside a common jacket of PVC or

industrial applications include med- ical devices for diagnosis and treat- ment; metrology; navigational aids for ships, machining, safety scan- ners, and automobiles. In many applications laser

diodes and their power supplies must be physically separate and therefore need appropriate intercon- nects. To limit voltage drop and sig- nal loss along the cable for pulsed lasers, the interconnect must offer both low resistance and extremely low inductance, also needed to main- tain rise and fall times within the nanosecond range required for the high power bursts.


Polyolephine resin. The resulting cables have extremely low induc- tance and a high capacitance. The BM Pulse Cables offer values of Characteristic Impedance from below ten Ohms to a maximum one Ohm for the heaviest type. The new BM Pulse Cable is


available in standard models with characteristic impedance values of 4, 2.5, 1.7 and 1.0W. Contact: Bridgeport Magnetics
