An improved table-top femtosecond soft X-ray laser with a gain duration of 450 fs is reported. The advent of X-ray free-electron lasers has granted researchers an unprecedented access to the ultrafast dynamics of matter on the nanometre scale1,2,3. Aside
Nanosecond pulsed laser ablation plasmas were studied by time resolved shadowgraphy coupled with normal imaging, followed by laser probing and plasma spectroscopy in the 5-25 J/cm2 fluence regime. We describe methods for imaging and probing that allow us to determine variations in the distribution ...
The changes in the principle of EHLC have resulted in significant changes in the setting of process parameters compared to CLC, as shown in Table 1. The laser spot diameter of the EHLC is much smaller (<1 mm) for achieving a higher laser power density (up to 3 KW/cm2), which is ...
Also, for a mirror set covering a given spectral region, lasing of individual lines may be accomplished using intracavity prism tuners. TABLE 11. Excitation Lasers of cw Dye Lasers LaserTransitionaWavelength (nm)Powerb (W) Ar+ 4p4D1/20−4s2P1/2 528.69 1.5 4p4D5/20−4s2P3/2 514.53 ...

Both grain refinement generation and CRS are responsible for improving the mechanical properties of materials. LSP treatment in additively manufactured materials has shown different effects on the tensile properties of the materials. Table 3 summarizes some results of the tensile properties of PBF ...
30KW Large Format Fiber Laser Cutting Table for Sheet Metal Ultra-large format fiber laser cutting table comes with a laser generator with 30KW power and customizable width and length for larger and thicker sheet metal. Fiber Laser Pipe & Tube Cutting Systems ...
If the issue of energy reproducibility can be addressed, it should be possible to generate ultrashort monoenergetic electron bunches of tunable energy, holding great promise for the future development of 'table-top' particle accelerators. 展开 ...
Laser-plasma technology promises a drastic reduction of the size of high-energy electron accelerators. It could make free-electron lasers available to a broad scientific community and push further the limits of electron accelerators for high-energy physics. Furthermore, the unique femtosecond nature of...
