Project sets records for laser performance

The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory recently produced 10,400 Joules or 10.4 kiloJoules (kJ) of ultraviolet laser light in a single laser beamline, setting a world record for laser performance. In recent weeks NIF laser scientists also have used the first four NIF beamlines to set records for infrared and green single beam laser energies with 21 kJ and 11 kJ of energy delivered, respectively. NIF researchers focused this light into a special diagnostic system designed to provide precise measurements of laser beam quality and performance at these different frequencies.

Semen quality may start to decline in one's 20s

With each passing year, semen quality in adult men declines, suggesting that age plays a greater role in male fertility rates than previously thought, according to a new study by researchers at the University of California, Berkeley, and Lawrence Livermore National Laboratory. The study, published Thursday, Feb. 6, in the journal Human Reproduction, suggests that even healthy men may become progressively less fertile as time goes by.

Researchers Apply Combat Simulation Technology to Homeland Security

Using a computer code originally developed for combat simulation, researchers from the Lawrence Livermore National Laboratory are supplying the same expertise that analyzes concepts of operation, technology and training to emergency responders as a part of the Lab’s role in homeland security. The Analytical Conflict and Tactical Simulation (ACATS) is an offshoot of the Joint Conflict and Tactical Simulation (JCATS) that the military uses for training, analysis, mission planning and mission rehearsal. JCATS also has been used to support actual military operations in places such as Panama and the Persian Gulf.
