We present spatial coherence measurements of extreme-ultraviolet light generated using the process of high-harmonic upconversion of a femtosecond laser. Using a phase-matched hollow-fiber geometry, the generated beam is found to exhibit essentially f

Traditional hole-sealing materials have some disadvantages such as long concretion time, poor airtightness caused by shrinkage and xerochasy and so on under the condition that drilling hole of water-bearing coal seam passes fissure zone. A new type o
