Demonstration of a High Average Power Tabletop Soft X-Ray Laser

چکیده
We report the first demonstration of a high average power tabletop soft x-ray laser. An average laser output power of ø1 mW s.2 3 1014 photonsysd was generated at 46.9 nm in Ne-like Ar using a very compact tabletop discharge. The spatially coherent average power emitted by this 26.5 eV laser is comparable to that generated at this photon energy in a similar bandwidth sDlyl 1024d by a thirdgeneration synchrotron beam line. Lasing was obtained at a repetition rate of 7 Hz with an average output energy of 135 mJypulse by exciting a plasma column in a ceramic capillary with a fast current pulse. This very compact high-repetition-rate laser source makes intense short-wavelength coherent radiation accessible to a wide variety of new applications. [S0031-9007(98)08022-3]

Generation and application of a high-average- power polarized soft-x-ray laser beam
We demonstrate the generation of a highly polarized soft-x-ray beam with a compact high-repetition-rate tabletop soft-x-ray laser. The radiation emitted by a high-average-power discharge-pumped tabletop Ne-like Ar soft-x-ray laser operating at 46.9 nm was polarized with a pair of Si/Sc multilayer mirrors designed for 45° operation. A degree of polarization greater than 0.96 was obtained. The po...

We report the uninterrupted operation of an 18.9 nm wavelength tabletop soft x-ray laser at 100 Hz repetition rate for extended periods of time. An average power of about 0.1 mW was obtained by irradiating a Mo target with pulses from a compact diode-pumped chirped pulse amplification Yb:YAG laser. Series of up to 1.8 x 10(5) consecutive laser pulses of ~1 µJ energy were generated by displacing...

We report the demonstration of a diode-pumped chirped pulse amplification Yb:YAG laser that produces λ=1.03 μm pulses of up to 1.5 J energy compressible to sub-5 ps duration at a repetition rate of 500 Hz (750 W average power). Amplification to high energy takes place in cryogenically cooled Yb:YAG active mirrors designed for kilowatt average power laser operation. This compact laser system wi...

We report the demonstration of a gain-saturated 10.9 nm tabletop soft x-ray laser operating at 1 Hz repetition rate. Lasing occurs by collisional electron impact excitation in the 4dS01-->4pP11 transition of nickel-like Te in a line-focus plasma heated by a chirped-pulse-amplification Ti:sapphire laser. With an average power of 1muW and pulse energy up to approximately 2microJ, this laser exten...
متن کاملContinuous high-repetition-rate operation of collisional soft-x-ray lasers with solid targets.
We have generated a laser average output power of 2 microW at a wavelength of 13.9 nm by operating a tabletop laser-pumped Ni-like Ag laser at a 5 Hz repetition rate, using a solid helicoidal target that is continuously rotated and advanced to renew the target surface between shots. More than 2 x 10(4) soft-x-ray laser shots were obtained by using a single target. Similar results were obtained ...
