As diode pumped solid state lasers (DPSSL) become more common there is a need to drive these pump diode arrays in a compact, efficient and cost-effective manner. The LLNL system for controlling high current laser diode arrays is an integrated system for meeting the needs of driving laser diode arrays in a DPSSL. The system is comprised of technologies required to control the DPSSL that…

LLNL researchers have demonstrated a novel single-shot recording technology for transient optical signals in a time regime of picoseconds to nanoseconds for which currently there is a significant instrumentation gap.

The optical switching capability of optical semiconductors can be exploited in a pump-probe style architecture, where an auxiliary pump beam is crossed through the signal…

The selected industrial partner and LLNL will enter into a Cooperative Research and Development Agreement (CRADA) to develop the next generation of laser technologies for MEGa-ray systems and to create a next generation of MEGa-ray sources that could be marketed to both the industrial and academic communities.

The MEGa-ray system developed will be based on LLNL's proprietary, multi-…

The SLIDER deflector includes a waveguide, a serrated mask positioned above the waveguide cladding, and a synchronized pump beam. The pump beam illuminates the serrated mask with a short pulse and transfers its pattern to the guiding layer where it imprints a sequence of prisms. The prisms are activated via nonlinear optical effects in the semiconductor and persist for the duration of the…
