IPC: E02D17/08
Filed: 1985-06-27
Abstract: A cribbing device for trenches which includes a pair of opposing supports spaced apart by a spreader, each support having a plurality of guide profiles and a crosspiece. The crosspiece is disposed transversely to the longitudinal axis of the trench, and the guide profiles are arranged adjacent each other on said crosspiece. The guide profiles include a plurality of legs disposed vertically and extending outward from the crosspiece, and a plurality of flanges disposed vertically and secured to the legs at the ends of the legs opposite the crosspiece. The flanges project beyond both sides of the legs. A plurality of cribbing boards each having a guide bar which supports a guide head is provided. The guide head is in the form of a slotted hollow box section and extends vertically beyond the board at its vertical face side. The width of each guide profile flange is slightly smaller than the inside width of the guide heads. The slot of the guide heads corresponds to the legs of the guide profiles, and the inside spacings between the legs of the adjacent guide profiles is slightly larger than the total width of the guide heads. The boards may, therefore, be guided and supported by the supports by engaging the guide heads of the boards with the guide profiles of the supports thereby permitting the boards to be passed by each other on parallel planes and to be supported by the supports in a form-locked manner.

Title: 圆柱形排布的脉冲双包层光纤放大器
Inventor: LOU QIHONG
IPC: H01S3/00
Filed: 2003-01-10
Abstract: 一种圆柱形排布的脉冲双包层光纤放大器，是将多模双包层光纤排布成一定直径的圆柱形，将高光束质量的低功率脉冲激光作种子光源，沿着圆柱体的一条圆外切线去掉双包层光纤的外包层，形成一长条内包层耦合泵浦窗口，与它相对的有长发光面的半导体激光泵浦源和焦斑呈线状的聚焦透镜，种子源激光器发出的线偏振脉冲激光通过1/2波片和1/4波片，变换为合适偏振态的脉冲激光，耦合进双包层光纤的纤芯，经圆柱形排布的双包层光纤放大器放大后，高功率的脉冲激光由双包层光纤的另一端输出。本发明具有结构紧凑、泵浦均匀、泵浦效率高的特点，能够输出高能量、高光束质量的单偏振脉冲激光。
