In the present embodiment, Ermy-Gaussian beam refers to that light field meets:
Light beam, wherein H
m(x), H
ny () is Hermite Polynomials, the value of m, n determines the form of Hermite-Gaussian Beams, can be changed the shape of Hermite-Gaussian Beams by the value changing m, n.
Hermitian function of a complex variable Gaussian beam refers to that the independent variable unit of Hermite Polynomials is function of a complex variable, that is:
Owing to there is complex item thus Hermitian function of a complex variable Gaussian beam there will be dark core, the shape of dark core, size and position can be controlled by the value changing m, n in function of a complex variable Hermite Polynomials.
In the present embodiment, there is the dark core light beam in various center in second-order Hermitian function of a complex variable Gaussian beam, can by changing transverse intensity distribution factor b (the transverse intensity distribution factor, Main Function is the intensity profile on control phase mask Figure 90) make it have a dark core or two dark cores, can also change the size and shape of dark core further, these characteristics can be used to the microscopic particle carrying different size and shape simultaneously; And second-order Hermitian function of a complex variable Gaussian beam self can rotate, this makes second-order Hermitian optical beam ratio generic central dark core light beam more meaningful, can be widely used.

In the present embodiment, described device 100 gets a kind of situation of common Hermitian function of a complex variable Gaussian beam: second-order Hermitian function of a complex variable Gaussian beam is to produce light beam.
In addition, in the present embodiment, the second-order Hermitian function of a complex variable Gaussian beam obtained through spatial light modulator 50 is defined as formula (2 ') in the Electric Field Distribution of transmission range z=0
Wherein b is the transverse intensity distribution factor, and Main Function is the intensity profile on control phase mask figure.W0 is the beamwidth producing second-order Hermitian function of a complex variable Gaussian beam.
Huygens-fresnel diffraction integral formula is formula (3) in the expression formula of rectangular coordinate:
When propagating in free space, it is formula (4) that second-order Hermitian function of a complex variable Gaussian beam obtains Electric Field Distribution under near field:
W in formula
0represent the beamwidth of light beam, λ represents wavelength, and k=2 π/λ represents wave number, and z represents propagation distance, and x, y represent rectangular coordinate, and b is the distribution factor of second-order Hermite-Gaussian Beams, can control beam pattern;
