Abstract
The generation of high brightness soft X-ray laser pulses were demonstrated by high harmonic seeding of a table-top soft X-ray laser plasma amplifier created by heating a solid titanium target with short optical laser pulses. The soft X-ray laser amplifier was created by heating a dense precreated titanium plasma with a 0.8 J optical laser pulse of 6.7 Ps duration impinging at a grazing incidence angle of 23 degrees. The high harmonic pulses were generated in an argon gas cell and relay imaged them at the entrance of the soft X-ray laser amplifier using a toroidal mirror. The resulting soft X-ray beam laser is essentially fully spatially and temporally coherent. The high harmonic seeding of collisional soft X-ray laser amplifiers generated by heating solid targets was scalable to shorter wavelengths and pulse widths of a few hundred femtoseconds, and should lead to table-top soft X-ray lasers of extremely high peak brightness.
