Abstract
The Laser Plasma Division of the Raja Ramanna Centre for Advanced Technology (RRCAT), Indore has been engaged in research and development activities on laser plasma interaction using a 10 TW, 45 fs, Ti:sapphire laser and a variety of in-house developed diagnostic systems for ultrashort laser pulses, plasma, and x-ray radiation. Our recent studies include high order harmonic generation and optimization, laser driven electron acceleration, enhancement of x-ray yield in the water-window spectral region, ultrashort high brightness K-alpha x-ray generation, and MeV energy bremsstrahlung radiation. This paper briefly describes these studies and the important results obtained.
