Abstract
A broad bandwidth laser beam can help provide uniform illumination on fusion targets by reducing intensity modulations caused by coherent constructive interference of the laser beam in or near the focal volume. A pulsed laser oscillator has been developed that utilizes the naturally broad gain bandwidth of Nd:glass and the relatively wide free spectral range of a 50-μm thick quartz etalon to produce pulses at 1.054 μm with spectral shapes as wide as 50 Å.
