Title: Management and utilization of ase in optical amplifier
Inventor: YADLOWSKY MICHAEL J
IPC: H01S3/23
Filed: 1999-09-17
Abstract: An amplification stage of a multistage, rare earth doped (10) amplifier, having a gain spectrum including a shorter wavelength band and a longer wavelength band, provided with excitation light produces an amount of ASE  traveling in a reverse direction to the initial excitation light. The reverse traveling ASE light is directed to another amplification stage (14) of the amplifier (10) and substantially provides excitation light for pumping the longer wavelength band. The proposed amplifier structure and associated method of optical signal amplification efficiently utilizes unavoidable ASE light for optical signal amplification. The invention provides signal amplification in a wavelength band not heretofore efficiently utilized in conventional rare earth doped optical amplifiers.

Title: Device for increasing heat transfer
Inventor: EDGREN ANDERS
IPC: F28F13/10
Filed: 1999-11-23
Abstract: The present invention relates to the problem of obtaining a device for increasing the heat transfer from an object (3; 73; 103). The problem is solved by means of a device (1; 71; 101) comprising one or more oscillating membranes (21, 25; 81; 121, 125) for generating an air motion of air surrounding the object (3; 73; 103). Further, the device comprises means (31, 33; 87; 129, 131) for affecting the air motion so that this causes a continuous exchange of air surrounding the object (3; 73; 103). The continuous exchange of the surrounding air means that the object (3; 73; 103) is surrounded by relatively cold air all the time, and therefore the heat transfer from the object (3; 73; 103) to the surrounding air is efficient.
