Question

5. A high energy pulsed laser emits 4.50 nano second-long pulse of average power 1.50 x 1011 w. The beam is cylindrical with 2.20 in radius. Determine the rms value of the E-field? NC 6. Three polarizing disks whose planes are parallel and centred on common axis. The directions of their transmission axes relative to the vertical are respectively: 01-39 clockwise, 02 15° counter-clockwise, and 03-23 clockwise. A beam of light polarized along the vertical is incident onto the first polarizer with an intensity of l 50 W/m2. Calculate the transmitted intensity through all three polarizers WIm2

Explanation / Answer

Problem 5)

Energy delivered, W= Pt = 1.50*1011*4.50*10-9 = 675 J

A = r2 = *(2.2*10-3)2 =1.52*10-5 m2

Erms = (P/Aco) = (1.5*1011/1.52*10-5*3*108*8.85*10-12) = 1927.60*106 N/C
