Abstract
Methods and systems are provided for separating polarized UV light. In one example, a method may include passing polarized source light through a group of at least four prisms to collimate and separate a second-harmonic generation (SHG) beam from a pump beam. The separated SHG beam may then be further passed through a spatial filter to reduce spatial distribution.

A method, comprising:
- collimating a polarized source light;
- passing the collimated polarized source light through a first prism pair to separate a second-harmonic generation (SHG) beam from a pump beam;
- and
- then passing the SHG beam through a third prism to compensate for dispersion in the SHG beam, the polarized source light including the SHG beam and the pump beam.

A method, comprising:
- passing polarized source light through a first prism pair to separate a plurality of second-harmonic generation (SHG) beams from a pump beam;
- and
- then passing the plurality of SHG beams through a second prism pair to compensate for dispersion in the plurality of SHG beams, the polarized source light including the plurality of SHG beams and the pump beam.
A chromatography system, comprising:
- optics providing a polarized laser source light;
- a prism group comprising four prisms positioned downstream of the optics;
- a lens group comprising one or more lens positioned between the optics and the prism group;
- a converging lens positioned downstream of the prism group;
- a sample and a detector positioned downstream of the converging lens;
- and
- a control unit including instructions stored in non-transitory memory to:
- pass a polarized light source through each of a first prism and a second prism of the prism group to separate an ultraviolet (UV) light from a fundamental light;
- then pass the UV light through a third prism and a fourth prism of the prism group to remove dispersion of the UV light;
- then pass the UV light through the converging lens to reduce spatial distribution of the UV light;
- and
- then pass the UV light through the sample and the detector for characterizing the sample.
