Abstract
An investigation was made of a laser (Nd:YLF/Nd glass) laser system ge nerating pulses of 1.5 ps duration and up to 0.4 TW power at the 1053 nm wavelength. Chirped pulse amplification in a multipass amplifier wa s used. The amplifier had a misaligned conjugate cavity and a net gain of similar to 4 X 10(6), as well as two additional amplifiers with an output aperture 20 mm in diameter. After optimisation of the paramete rs of this multipass amplifier the angular divergence of the output ra diation was close to the diffraction limit and the average intensity w as up to similar to 10(17) W cm(-2) in a focused beam. This laser syst em was developed as the front-end component of a multiterawatt laser f acility under construction for research on the interaction of ultrastr ong fields with matter.
