Title: Fiber optic amplifier
Inventor: SHAW HERBERT J
IPC: H01S3/23
Filed: 1984-09-29
Granted: 1992-08-10
Abstract: @ A pair of small diameter optical fibers (12, 14) are arranged in a side-by-side configuration, the first fiber (12) providing a passive guide for pump light, and the second fiber (14) formed of a material, such as Nd:YAG which has amplifying properties at the signal frequency. The signal to be amplified propagates through the second fiber (14) resulting in amplification of the signal. The first fiber (12) is pumped from one or both ends, utilizing a cone shaped rod (50) which is optically coupled thereto. A plurality of pump light sources (60) are mounted on the end face (58) of the rod (50) to introduce collimated pump light into the large end (52) of the cone shaped rod (50). Total internal reflections on the cone walls compress the pump light to a small, fiber-size diameter end (54) for propagation through the pump fiber (12) and absorption by the active fiber (14). The pump light sources (60) are offset from the axis (72) of the rod (50) to excite high order modes in the pump fiber (12) to enhance absorption by the active fiber (14). The pump light sources (60) preferably comprise high power laser diodes (64) and collimating microlenses (62). By utilizing the cone-shaped rod (50) to couple light from the high power laser diodes (64) to the pump fiber (12), high pump power densities can be achieved, yielding increased amplification.

Abstract: A resonance rate lowers when oscillation generated at the compressor's operating part is transmitted to the shell.  A curve is given to a straight line part and a spherical surface is given to a plane to lower oscillation with the max.  A non symmetric character is maintained at a lateral section or a longitudinal section, so that the oscillation and the resonance rate, resp. generated at the operating part, are lowered.  The amplification of the oscillation, generated when the resonance starts, is ineffectually induced to the least to reduce the noise to the minimum.
