Laser and detector system for LIDAR plasma diagnostics based on Thomson scattering measurements

Creators

Description

The Neodymium-glass laser with output energies between 10 and 30 Joules in 0.3 nanosecond pulses is able to satisfy the requirement of about 10 cm for the spatial resolution of the electron temperature measurement based on Thomson scattering in the ITER experiment. For this purpose a classical laser scheme for a LIDAR Thomson scattering system is discussed. The main advantages in comparison with the direct amplification scheme with large aperture active elements are (i) high efficiency, durability, and reliability, and (ii) lower requirements to the optical elements of the system due to the wave front reversal effect. 4 refs, 14 figs, 1 tab
