“…An analysis of (55) shows that if 2 2 < 1, squeezing is greater in harmonic mode compared to fundamental mode. Further, a comparison between the results of (30), (38), (41) and (55) with our earlier work [42] it is observed that the squeezing and sub-Poissonian effects of light are more pronounced to reduce the quantum noise in the fifth harmonic generation than the corresponding squeezing and sub-Poissonian effects of light in the fourth harmonic generation.…”

The nonclassical effects of light in the fifth harmonic generation are investigated by quantum mechanically up to the first-order Hamiltonian interaction. The coupled Heisenberg equations of motion involving real and imaginary parts of the quadrature operators are established. The occurrence of amplitude squeezing effects in both quadratures of the radiation field in the fundamental mode is investigated and found to be dependent on the selective phase values of the field amplitude. The photon statistics in the fundamental mode have also been investigated and found to be sub-Poissonian in nature. It is observed that there is no possibility to produce squeezed light in the harmonic mode up to first-order Hamiltonian interaction. Further, we have found that the normal squeezing in the harmonic mode directly depends upon the fifth power of the field amplitude of the initial pump field up to second-order Hamiltonian interaction. This gives a method of converting higher-order squeezing in the fundamental mode into normal squeezing in the harmonic mode and vice versa. The analytic expression of fifth-order squeezing of the fundamental mode in the fifth harmonic generation is established.
