Abstract
A laser system includes a laser element, a pump source configured to input light to the laser element, a first heat exchanger, a pump source heat exchanger, a laser element heat exchanger, and a pump. The first heat exchanger is configured to cool a first flow of cooling liquid. The pump source heat exchanger is configured to remove heat from the pump source using the first flow of cooling liquid. The laser element heat exchanger is configured to remove heat from the laser element using a second flow of cooling liquid. The pump is configured to drive the first and second flows of cooling liquid.
Claims20
A laser system comprising:
- a laser element;
- a pump source configured to input light to the laser element;
- a first heat exchanger configured to cool a first flow of cooling liquid from a first source;
- a pump source heat exchanger configured to remove heat from the pump source using the first flow of cooling liquid;
- a laser element heat exchanger configured to remove heat from the laser element using a second flow of cooling liquid from a second source;
- and
- at least one pump configured to drive the first and second flows of cooling liquid,
- wherein the second source is configured to receive a portion of the first flow of cooling liquid output from the first heat exchanger.
