Paper Abstract

The average power performance capability of semiconductor diode laser arrays has improved dramatically over the past several years. These performance improvements, combined with cost reductions pursued by LLNL and others in the fabrication and packaging of diode lasers, have continued to reduce the price per average watt of laser diode radiation. A low cost technique developed and demonstrated at LLNL for optically conditioning the output radiation of diode laser arrays has enabled a new and scalable average power diode-end-pumping architecture that can be simply implemented in diode pumped solid state laser systems (DPSSLs). This development allows the high average power DPSSL designer to look beyond the Nd ion for the first time. Along with high average power DPSSLs which are appropriate for material processing applications, low and intermediate average power DPSSLs are now realizable at low enough costs to be attractive for use in many medical, electronic, and lithographic applications.
