Abstract
Methods and apparatus for maintaining a quality of a Raman medium in a Raman conversion cell. In various examples, a flow velocity of the Raman medium is tailored based on a spatial nonuniformity of heat deposition resulting from the Raman conversion in the cell. In particular, in one example, the flow velocity of the Raman medium may be tailored to be higher where the heat deposition/temperature rise is larger and smaller elsewhere in the cell. This type of flow velocity profile reduces the overall required volumetric flow of the Raman medium in the cell without significantly affecting a quality of the Raman medium.
Claims26
In a Raman conversion cell containing a fluid Raman medium, a method comprising an act of:
- a) reducing a total volumetric flow of the fluid Raman medium through the Raman conversion cell while maintaining a quality of the fluid Raman medium.
An apparatus, comprising:
- a Raman conversion cell configured to contain a fluid Raman medium flowing therethrough, the Raman conversion cell being further configured to reduce a total volumetric flow of the fluid Raman medium through the Raman conversion cell while maintaining a quality of the fluid Raman medium.
A Raman cell, comprising:
- a cavity configured so as to allow the propagation therethrough of at least one radiation beam, the cavity having at least a first segment coupled to a second segment, the cavity further configured such that the first segment has a first width and the second segment has a second width, the first width being smaller than the second width.
A Raman cell, comprising:
- a cavity configured so as to allow the propagation therethrough of at least first radiation and second radiation, the cavity having a first portion and a second portion separated by a divider wherein first portion has at least one smaller dimension than the second portion, the cavity being further configured such that the first radiation passes through the first portion and the second radiation passes through the second portion.
