Systems, Methods, And Devices For Optical Output Generation

A system comprising:

• a light source configured to generate a beam of a first light having a first wavelength;
• a plurality of optical elements configured to receive the beam of the first light, the plurality of optical elements being further configured to change a spatial distribution of the beam of first light to an annular spatial distribution;
• a focusing element configured to receive a first optical output of the plurality of optical elements, and further configured to focus the first optical output at a focal point;
• an interaction medium positioned at the focal point and configured to undergo high-harmonic generation of a second light having a second wavelength based on the first light;
• and
• an optical aperture configured to block first light that passes through the interaction medium, and further configured to transmit the second light as a second optical output.

A method comprising:

• receiving, at a plurality of optical elements, a beam of a first light from a light source, the first light having a first wavelength,
• changing, using the plurality of optical elements, a spatial distribution of the beam of first light to an annular spatial distribution;
• focusing, using a focusing element, the beam at a focal point;
• generating, using an interaction medium positioned at the focal point, a second light having a second wavelength, the second light being generated via high-harmonic interactions;
• and
• blocking, using an optical aperture, first light that passes through the interaction medium and transmitting the second light as a second optical output.
