Application No. 92/CHE/2011 Published on Dec. 9, Assigned to Sumitomo Electric Industries for Laser Apparatus (Japanese Inventors)

MUMBAI, India, Dec. 20 — Shinobu Tamaoki and Motoki Kakui, both of Japan, have developed a laser apparatus. Application No. 92/CHE/2011 was filed on Jan. 11, and published on Dec. 9.

The application has been assigned to Sumitomo Electric Industries Ltd., Osaka, Japan.

According to the abstract released by the Intellectual Property India: “The present invention relates to a laser apparatus capable of supplying laser beams from each of plural beam emitting ends constituting laser beam output ports, and realizes the overall low power consumption and low non-linearization. The laser apparatus comprises a seed light source, beam emitting ends, an intermediate optical amplifier, an optical branching device, and final-stage optical amplifiers. The number of beam emitting ends is greater than the number of seed light sources, and the final-stage optical amplifiers and the beam emitting ends correspond to each other one-on-one. The optical branching device includes an input port associated to the seed light source and plural output ports associated to the respective beam emitting ends so as to constitute a part of the light paths between the seed light source and the beam emitting ends. The intermediate optical amplifier is disposed on the light path between the seed light source and the optical branching device, while the final-stage optical amplifiers are respectively disposed on the branch lines between the beam emitting ends and the optical branching device.”
