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

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 I_t= I_isin²(Î”Ï†/2).

Make a plot of I_t/I_i 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 I_t to be zero for ADP (Î»₀ = 546.1 nm)? How can things be rearranged to yield maximum value of I_t/I_i for zero voltage? In this new configuration what irradiance results when V = V_Î»/2?
