Mid-infrared laser absorption-based sensors for trace gas detection using difference-frequency generation
Real-time, compact, laser absorption-based sensors for trace gas detection have been developed. Difference-frequency generation in a periodically poled lithium niobate (PPLN) crystal pumped by two compact lasers, a ...
Longitudinal magnetic media with soft magnetic under-layers read with magneto-resistive heads
Keepered media refers to traditional magnetic media with the addition of a soft magnetic "keeper" layer adjacent to the recording layer. Numerous recent reports have shown performance improvements associated with keepered ...
