Picosecond soft-x-ray pulses from a high-intensity laser-plasma source
- INRS-Energie et Materiaux, 1650 Montee Ste.-Julie, Varennes, Quebec J3X 1S2 (Canada)
We report time-resolved spectroscopic analysis of laser-produced plasma x-ray sources. Plasmas produced by a 400-fs 1-TW tabletop laser are characterized with a transmission grating spectrometer coupled to a soft-x-ray streak camera. Soft-x-ray radiation in the 1{endash}6-nm range with durations of 2{endash}7ps is observed for copper and tantalum plasmas. The effect of incident laser energy on the x-ray pulse duration is also investigated. {copyright} {ital 1996 Optical Society of America.}
