| 20090285528 | CLADDING GRATING AND FIBER SIDE-COUPLING APPARATUS USING THE SAME - A fiber side-coupling apparatus can be spliced with active fiber as a fiber-based side-coupler in series at both sides for distributively-pumped monolithic fiber lasers. This side-coupling apparatus includes a large-mode-area double-clad passive optical fiber. A cladding grating, formed on the cladding surface of the passive fiber, comprises a plurality of grating members and a reflection layer formed thereon. A laser diode bar array is disposed on one side of the optical fiber opposite the cladding grating. A collimation device, placed between the optical fiber and the laser diode bar array, is used to collect the pump beam to the cladding grating as much as possible in fast axis and collimate the pump beam to be incident to the cladding grating in slow axis as normally as possible. The collimated pump beams emitted from a laser diode bar array are normally incident to the cladding grating within the alignment tolerance of ±2 to ±4 degrees. Without the reentrance loss effect, the pump beams diffracted and reflected by the cladding grating propagates in the inner cladding of the passive fiber due to total internal reflection. In one embodiment, the grating member can be a binary or blazed cross section. | 11-19-2009 |
| 20100137851 | LASER SURGICAL APPARATUS - A laser surgical apparatus is provided. The laser surgical apparatus includes a laser generator, a laser delivery module for delivering a laser beam to biological tissues, a fluid source, a fluid delivery module for delivering a fluid to the biological tissues, and a control module for controlling all the above units. | 06-03-2010 |
| 20100142563 | FIBER LASER DEVICE - A fiber laser device includes a laser pump for irradiating a laser beam, an optical component, an optical fiber and an optical sensor. The optical component has a first and a second output end, wherein a portion of the laser beam is output from the first output end and another portion of the laser beam is output from the second output end. The optical fiber including a core and a cladding layer is optically coupled between the laser pump and the optical component. A inclined angle θ of the first output end satisfies the following relations that θ | 06-10-2010 |
| 20110026892 | OPTICAL FIBER STRUCTURE WITH FILTERING THIN FILM - An optical fiber with filtering thin film includes a first ferrule having a first through hole and a first contact surface. A first fiber is disposed into the first through hole, extending to the first contact surface. A first interface coupling material is between the first ferrule and the first fiber. A second ferrule has a second through hole and a second contact surface. A second fiber is disposed into the second through hole, extending to the second contact surface. A second interface coupling material is between the second ferrule and the second fiber. The first contact surface and the second contact surface are parallel and have an included tilt angle from a perpendicular transverse plane of first fiber. An optical filtering film is disposed between the first contact surface and the second contact surface. The first fiber and the second fiber are aligned. | 02-03-2011 |
