A handheld tool carrying case having a carrying case base and a carrying case cover and at least one electronic system. The handheld tool carrying case has a lighting device and an orientation device, which are provided to fixate at least one part of the carrying case base or of the carrying case cover pivotably in various orientations relative to a resting plane of the carrying case base or of the carrying case cover.
摘要:
A handheld tool storage device, particularly to a handheld tool carrying case, having at least one base body unit which includes at least one movably supported base body element, and having at least one electric functional unit, and having at least one operating unit at least for operating the electric functional unit. The operating unit has at least one operating element that is at a minimum distance from an axis of motion of the base body element, which is less than 50% of a main extension of the base body element.
摘要:
A novel narrow linewidth laser device is disclosed that includes a gain element, such as a quantum well, quantum dot or bulk waveguide laser chip and a fiber Bragg grating formed in an optical fiber positioned to receive the output from a first end of the gain element and return a portion of said output back into the gain element. The fiber Bragg grating is constructed so that its power reflectivity profile has a ratio of reflectivity slope over reflectivity at the 3 dB point below the reflectivity peak on the red side (longer wavelength side) of the grating larger than a value of 2/nm. The operating wavelength of the device may be tuned thermally, electrically, or thermo-electrically to be on the red side of the fiber Bragg grating reflectivity profile, preferably, but not necessarily, at the 3 dB point below the reflectivity peak or lower. In another embodiment, a second grating is optically coupled to a second end of the gain element and has a reflectivity profile that overlaps at least a portion of the reflectivity profile of the front end fiber Bragg grating.

摘要:
A novel narrow linewidth laser device is disclosed that is formed monolithically on a semiconductor substrate, such as an indium phosphide substrate, that includes a continuous waveguide with a gain section and a grating section wherein a grating is constructed so that its power reflectivity profile has a ratio of reflectivity slope over reflectivity at the 3 dB point below the reflectivity peak on the red side (longer wavelength side) of the grating larger than a value of 2/nm. The operating wavelength of the device may be tuned thermally, electrically, or thermo-electrically to be on the red side of the fiber Bragg grating reflectivity profile, preferably at the 3 dB point below the reflectivity peak or lower. In another embodiment, a second grating is formed on a second grating section of the waveguide on the opposite side of the gain section than the first grating section and wherein the reflectivity profile of the second grating overlaps at least a portion of the reflectivity profile of the first grating.
