Embodiments of a laser system having an extremely large number of small pulsed lasers for irradiating small targets in inertial confinement fusion experiments, high energy density physics experiments, and inertial fusion power plants is more flexible than existing laser systems. Embodiments facilitate finer control of critical features of laser pulses for inertial fusion, as well as significant reduction in development costs and expansion of the community involved in the research relative to existing laser systems. Embodiments produce smooth intensity profiles at the target, large bandwidth that is over two orders of magnitude greater than existing laser systems, and fine control over laser wavelengths, focal properties, temporal pulse shape, and illumination geometry. Properties of each of the small pulsed lasers are individually selectable.

Flexible driver laser for inertial fusion energy

A continuous-wave (CW), ultraviolet triply-optically-pumped atomic laser (TOPAL) is disclosed. The inventive laser device includes a laser active media comprising a mixture of a neutral atomic vapor and one or more buffer gases. The gain mixture is placed within a segmented gain cell, allowing for periodic, selected spectral filtering of deleterious ASE transitions; the segmented gain cell, in turn, is placed within an optical cavity with a high Q at a specified ultraviolet wavelength, and is successively, resonantly excited by three drive pump lasers, in three energy-contiguous visible/IR electric-dipole allowed transitions, producing a steady-state electron population inversion density between a high-lying electronic energy level and the ground electronic level, and producing laser emission on a UV transition (within the spectral range &#x2dc;230 to &#x2dc;370 nm) terminating on the ground electronic level.
