Abstract: The metallic card wire (100) includes a rib portion (110) and a plurality of teeth (115). The teeth have a tip segment (117), a front portion (120), a back portion (130), two sides (141, 142) and an interconnection section connecting the back portion of a tooth to the front portion of the previous tooth. The teeth lean in the card wire longitudinal direction. The teeth's front portion leans towards the longitudinal direction. The front portion includes an undercut segment where the included angles of the tangents to the front portion with the longitudinal direction of the card wire are smaller than the included angles of the tangents to the front portion with the longitudinal direction of the card wire between the undercut segment and the tip segment. At least one side of the teeth includes at least a first structural element for increasing the frictional force of fibers relative to the side of the teeth and positioned closer to the tip segment compared to the undercut segment's position.

Abstract: A multi-wavelength single-frequency optical fiber laser source for a laser radar system includes a resonant cavity composed of a high-reflectivity chirped optical fiber grating, a high gain optical fiber and a low-reflectivity chirped optical fiber grating, a single-mode semiconductor pump laser served as a pump light source, an optical wavelength division multiplexer, an optical coupler, an optical isolator, an optical circulator, an optical filter module, and a semiconductor optical amplifier. The pump light source performs optical fiber core pumping with respect to the high gain optical fiber. A portion of the wide-spectrum laser is filtered by the optical filter module to obtain a wavelength corresponding to a specific central frequency. Multi-wavelength laser lasing with a narrow linewidth and single longitudinal mode is implemented by combining a short linear resonant cavity structure and the optical filter module.

Abstract: The card wire comprises a plurality of teeth inclined at an angle with the rib portion. The teeth have a front portion and a back portion joining at the tip of the teeth; and a base segment connecting the front portion to the back portion of the preceding tooth. The front portion is the inner portion of the tooth leaning towards the rib portion. The back portion is the outer portion of the tooth. The front portion comprises at least two undercut segments. The second undercut segment is spaced further away from the tip of the tooth than the first undercut segment. Each undercut segment has an undercut angle, being the minimum of the angles with the longitudinal direction of the card wire, of the tangents to each point of the part of the undercut segment going—when observed from the tip—inwards from the front portion.

The front segment has the connection of the tooth from the elongated rib portion and the front segment including a tip which is actively taking fibers in carding. The top segment has at least one hunch after the tip in the direction of the back segment. If more than one hunch is present the first hunch is the hunch positioned closest to the tip; if only one hunch is present this hunch is the first hunch. The back segment forms the connection of the top segment towards the elongated rib portion and the front segment of the next tooth.
