Question:

If the Pockels cell modulator shown in Fig. 8.65 is illuminated by light of irradiance Ii, it will transmit a beam of irradiance It such that It= Iisin2(Δφ/2).

Make a plot of It/Ii versus applied voltage. What is the significance of the voltage that corresponds to maximum transmission? What is the lowest voltage above zero that will cause It to be zero for ADP (λ0 = 546.1 nm)? How can things be rearranged to yield maximum value of It/Ii for zero voltage? In this new configuration what irradiance results when V = Vλ/2?
