Question

Consider the problem of second-harmonic generation using the output of a pulsed ruby laser ( 694 nm) in a KDP crystal. The refractive indices are given below: nefh 694 nm) 1.466, nel-347 nm) 1.490 no(A-694 nm) : 1.506, no(As 347 nm)-1.534 is birefringent phase matching possible for SHG? Calculate the phase matching angle, Writ.
