Plasma dispersion effect based super-resolved imaging
Disclosed herein is a super resolution imaging method and system for obtaining an image in a crystal material and/or device.
1. A super resolution imaging method for obtaining an image in a crystal, the method comprising:
i. providing a crystal;
ii. projecting:
a pump beam comprising a Gaussian beam or a doughnut beam into said crystal surface, thereby creating a free charge carrier (FCC) density pattern; and
a collinear probe beam into said crystal surface, thereby controlling the lateral and temporal transmission of said probe beam, wherein said free charge carrier (FCC) density pattern is controlled by a vortex plate with a topological order of 0 to 8.
2. A super resolution imaging system for obtaining an image in a crystal, comprising:
a laser configured to project a pump beam and a probe beam collinearly into said crystal surface;
a vortex phase plate positioned between said pump beam source and said crystal; and
a control unit configured to control the shape of said pump beam, thereby controlling the lateral and temporal transmission of said probe beam.
3. The system of claim 2 , wherein said control unit is configured to provide a predetermined beam pulse width and wavelength of said pump beam and said probe beam.
4. The system of claim 2 , wherein said control unit is configured to control said vortex phase plate topological order from 0 to 8.
5. The system of claim 2 , wherein said control unit is configured to control the distance of said pump beam focal point.
