Optical Fiber Communication Conference, 2017
• Optical fibers are an extraordinary active medium… • …but thermal effects cannot be simply neglected anymore. • Recently a serious new limitation has been discovered: Mode Instabilities. • This has quickly become the most limiting factor for the futher scaling of fiber systems.

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2004
The 20-year-evolution of high-power laser diodes with a multitude of device designs that explore various practical applications is presented. The four major applications for high-power diode lasers, namely pumps for EDFAs, YAG rods, disk lasers and fiber lasers have a tremendous impact on the selection process in this evolution.

High power ultrasound standard
The Journal of the Acoustical Society of America, 2002A sensitive radiation force balance for laboratory measurement of ultrasonic power is presented. The principle of the system is based on measuring the ultrasonic radiation force exerted on a conical float suspended in water. Technical details of the implementation of the economically attractive system are described.

Electrical Engineering, 1936
A brief outline of the essential characteristics of high power audio transformers for class B amplification (tubes connected in push-pull fashion with their grid voltages of such value that the anode current is zero when there is no signal) is given here together with a brief description of the units used in the third and fourth stages of ...

IEEE Transactions on Microwave Theory and Techniques, 1958
In order to obtain filters capable of handling very high power, the use of radial lines and uniform line discontinuities was investigated as the most promising approach. In this connection, it was necessary to consider equivalent circuit and interaction effects for H-mode radial line mated at each end to uniform TE 10 waveguide for taper angles of 45 ...

Proceedings of the IEEE, 1994
After the classification and a short review of the evolution, the different drive systems which became important in industrial applications are described. It is shown how motor, converter, and controls form a drive system. The specific characteristics of each system are emphasized in order to show which system is best suited for which kind of ...
