1.What is the average optical fluence of a tem laser beam, with a laser pulse enegy ET =2.5J? The pulse energy is evenly placed across the beam cross section at Rayleigh location z = 0. The wavelngth is 530nm, the divergence angle 0o is 3.39 x 10Prads, the half beam waist Wo is 10mm. (expression for F(p) in J.m2 below, where p is the radial parameter for a beam with radius Wz)
