Abstract
The use of the electron-ion collisional recombination process in an expanding, segmented plasma, has led to the development of a new class of metal-vapor lasers in the metals of Mg, Al, Ca, Cu, Zn, Ag, Cd, In, Sn, Pb, and Bi. These lasers operate in the ultraviolet at wavelengths as short as 298nm, in the visible, and in the infrared up to 1.950µm. These extremely simple lasers, which are easily constructed, have long operating life, and operate at repetition rates up to 1 kHz, produce output powers of 1–10 W/pulse for durations of 5–100µs. This type of laser, generated by a row of seamented arcs, is called a Segmented-Plasma-Excitation-Recombination laser or SPER laser.1 The extension of this type of laser excitation process to one that uses laser-produced plasmas as the excitation source is expected to lead to VUV and XUV lasers.
