The mixing efficiency in coherent lidar of an Airy signal field with a Gaussian local-oscillator(LO) is discussed with the consideration of the effect of wavefront matching of both fields.

The generalized even and odd coherent states (E-O CSs) of a finite-dimensional space non-harmonic oscillator are constructed, and their nonclassical properties are studied by numerical method.

Using the theoretics and properties of squeezed coherent state, the matrix elements of any power of coordinate operator for harmonic oscillator is deduced; and the result is discussed.
