Abstract
In one embodiment a laser amplifier includes a light pump source that can generate light at a first wavelength or range of wavelengths. The laser amplifier further includes an optically pumped laser amplifier having a gain medium that amplifies light at a second wavelength or range of wavelengths in response to receiving generated light from the light pump source. A housing is used to at least partially surround the gain medium and hold a coolant fluid able to absorb the second wavelength or range of wavelengths.

A laser amplifier, comprising:
- a light pump source configured to generate light at a first wavelength or range of wavelengths;
- an optically pumped laser amplifier having a gain medium that amplifies light at a second wavelength or range of wavelengths in response to receiving the generated light from the light pump source;
- and
- a light absorbing cladding that at least partially surrounds the gain medium and forms a flow cavity between the gain medium and the light absorbing cladding that holds a coolant fluid and an open-pore solid matrix,
- wherein the light absorbing cladding forming the flow cavity and the solid matrix absorbs light at the second wavelength or range of wavelengths from the optically pumped laser amplifier, and the coolant fluid flow through the solid matrix to remove waste heat from at least one of the solid matrix, the gain medium, and the light absorbing cladding.
