Numerical comparisons of the acceptance bandwidths for quasi-phase-matched E Zω E Zω–E Z2ω (ee–e) and EYω EYω–EZ 2ω (oo–e) second-harmonic generation processes in bulk periodically poled LiNbO3 (PPLN) are given. The larger acceptance ba

The velocity selection of the V-type three-level-atom mazer with atomic coherence is studied. It is shown that the atomic coherence can strongly affect transmission probability, and in turn, the velocity selection of atoms through the micromaser cavi

We study the spectrum of the micromaser injected with ultracold cascade three-level atoms. We examine the effects of the atomic centre-of-mass motion, the cavity length, the atom-field detuning, the ratio of the atomic injection rate to the cavity de

We derive the dressed states for the interaction of a cascade three-level atom with a quantum cavity field, suggest using ultra-cold cascade three-level atoms in micromasers, put forward the idea of the two-photon mazer, establish its general quantum

For second-order, third-order nonlinear optical (NLO) interactions in the bulk of a biaxial crystal, the optimum phase matching (PM) directions are generally taken in the first quadrant ( x , y , z >0) of the principal rectangular coordinate system.

For general parametric collinear four-wave mixing (FWM) or direct third harmonic generation (THG) processes involving fields at four different frequencies, the determination of the phase matching (PM) directions becomes considerably difficult. But th

We have analyzed the collinear phase matching (PM) conditions for third-harmonic generation (THG) in biaxial crystals and derived the expressions of the effective nonlinear optical susceptibility when PM directions are in the three principal planes u

Third-harmonic-generation processes in crystals are governed by the fourth-rank tensor ((3))(Xijkl), which reflects the crystal symmetry. In this case, the third-order nonlinear susceptibility tensor can be contracted to the compact matrix form ((3))

By analyzing the phase mismatch in the different frequency generation of noncollinear alignment, we obtain the condition in which noncritical phase matching can be realized. The relevant equation for determining the optimum angles between the inciden

We have characterized the properties of the phase-matching conditions of the organic nonlinear crystal meta-nitroaniline (m-NA) for second harmonic generation (SHG) and sum-frequency-mixing (SFM). The optical phase-matching conditions are measured an
