| Abstract: | We have demonstrated that we can homogenize the spatial profile of a high-energy green laser pulse used for pumping a petawatt scale Ti:sapphire amplifier. The second harmonic of a high-energy, large aperture Nd:glass laser system generates laser emission at a green wavelength with 75 J single pulse energy. Using a diffractive optical element for beam homogenization, we have obtained a highly spatially uniform flat-top second harmonic profile. |
