Abstract

Amplified spontaneous emissions of Li-and Be-like Al ions and Li-like Si ions were observed in recombining plasmas produced by a low-power driving laser. These were achieved by heating plasma with a train of laser pulses of short interval, and sharply focusing a pumping laser to a line 40 micrometers wide onto a slab target for rapid cooling of plasmas through adiabatic expansion. Mechanism of plasma heating and the optimum shape of the laser pulse for pumping soft X-ray lasers were also investigated.
