In California, the Stanford Linear Accelerator Facility (SLAC) and Lawrence Berkeley National Laboratory have chosen Sunnyvale-based Calmar Laser’s Cazadero, a femtosecond fiber laser chirped pulse amplifier system for synchronized time-resolved experiments that reveal structural changes in novel material systems. The system provides up to 20-μJ pulse energies at repetition rates up to a few megahertz and a typical pulse width of <500 fs. At SLAC, the technology is being used in experiments that could lead to the development of more efficient next-generation photovoltaic or biomedical materials. At Lawrence Berkeley, the Cazadero is enabling the development of a next-generation light source – a high-repetition-rate, high-brightness x-ray source that will enable cinematic imaging of dynamics, determination of the structure of heterogeneous systems and the development of novel nonlinear x-ray spectroscopies.
