High Power Efficient and Reliable Laser Bars (HiPER)
Abstract
(U) The goal of the High Power Efficient and Reliable Laser Bars (HiPER) program is to develop linear bars of laser diodes that are more than seventy percent efficient in converting electrical power to optical output power. These laser diode bars will be used for supplying the optical pump power to ytterbium (Yb) and neodymium (Nd) solid state lasers operating near 1060 nanometers (nm). Such high efficiency laser pumps will lead to dramatic reductions in the size and weight of 100 kW class diode pumped solid state lasers based on reduced size and weight of not only the electrical power supply, but also reduced size and weight of the thermal management system. The goal of the HiPER program is also to retain high wall-plug efficiency of over seventy percent while ultimately producing compact laser diode bars with more than 250 W/bar-cm at lifetimes of greater than 100 hours.
