Disclosed herein is an amplification method, an optical glass amplifier, a laser based on the amplifier and an amplification optical communication system, all based on a limited length of a single-mode glass fiber made from glass having phonon energy of less than about 350 cm.sup.-1 and doped with dysprosium. The glass includes 0.1-30 mol % germanium, 0-40 mol % arsenic, 0.01-20 mol % X, 0.01-20 mol % Y, and 0.001-2 weight % dysprosium, wherein X is selected from the group consisting of gallium, indium and mixtures thereof selenium; and wherein Y is selected from the group consisting of selenium, and mixtures of selenium and up to 50% of sulfur. The system includes a coupler, a silica-based signal fiber carrying the optical signal that is to be amplified in communication with said coupling means, a pump light source in communication with the coupler, an amplifier in communication with the coupler at one end and another silica-based fiber joined to the amplifier at its other end. The method includes the steps of introducing the optical signal to be amplified into the coupler, introducing a pump optical signal into the coupling means, combining the optical signal and the pump optical signal, introducing the combined optical signal into the amplifier and amplifying the optical signal by exciting the electrons in dysprosium so they emit at about 1.3 .mu.m.
摘要:
This invention pertains to a scene projection system and a method for projecting a scene that can simulate light temperature of above 2000 K. The system comprises of a light source part for generating light at a lower wavelength; a means part for individually controlling dynamic range, contrast, brightness, temporal characteristics and temporal dynamics of the light; a rare earth doped fiber part that re-emits the output light at a higher wavelength; and a means part for conveying light between its parts. The method comprises steps of generating light at a lower wavelength; individually controlling temporal characteristics, temporal dynamics, brightness and contrast of the light; passing the light through a rare earth-doped fiber; and re-emitting the light at a higher wavelength.

摘要:
The present invention is a device and method for applying a tanning solution. Generally, the method generates a fog by applying a predetermined pressure to a tanning solution, and then passing the solution through a nozzle such that the tanning solution under pressure produces a fog. The device generally includes a fog chamber with a fluid frame therein, the fluid frame having a plurality of nozzles disposed about it. The nozzles help achieve a fog by providing a disk fan to help disburse the fog away from a person being tanned.

摘要:
This invention relates to a cooking utensil with protrusions from its handle. While cooking, the utensils protrusions allow it to be rested on a pot or pan in order to prevent sauces and oils from dripping on stovetops, spoon rests, or other unwanted surfaces. Also since the utensil is held on the pot, bacteria and viruses cannot contaminate the utensil or food as easily. This invention also lends itself towards being quickly and easily placed and removed from its resting spot on the container, as well as minimizing workspace clutter by aligning its own handle with the handle of the container. This invention also has the means to be secure in its resting spot, which prevents it from falling into or to the side of the cooking container. Furthermore the invention can be easily manufactured by making small changes to the mold cavities and/or metal stamps currently used for utensil production.
