Progress toward ultrahigh intensities with the Titania krypton fluoride laser system
Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS 11 (1997) 523
Abstract:
Titania is the latest series of ultraviolet laser systems developed with the highest laser beam brightness. It can be configured in two alternative modes which can deliver a brightness of <1020 W cm-2 sterad-1. The first mode, used a chirped pulse amplification (CPA) to produce the shortest possible pulses. Values of 300 fs on the target are measured. The energy limitations of the CPA scheme are removed in the alternative architecture based on Raman beam combining. The Titania Raman system is designed to operate optimally with pulses of 30-500 ps duration.XUV Harmonic Generation By Ultra-intense (sub) Picosecond Laser Pulse Irradiation Of Solid Targets

Abstract:
Harmonic orders up to the 68th in first order diffraction and the 75th in second order have been observed during the interaction of a picosecond, 1053-nm laser pulse with a solid target for intensities of 10(19) Wcm(-2). Measurements of the conversion efficiency, spatial coherence, and angular distribution show that this source has already achieved a spectral brightness second only to collisional XUV lasers. Future directions of investigation are outlined.Imaging of high harmonic radiation emitted during the interaction of a 20 TW laser with a solid target
