Abstract
A laser system may include a first portion of laser host material adapted for amplification of laser radiation and a second portion of laser host material surrounding the first portion which may be adapted for suppression of ASE. The first portion of laser host material and the second portion of laser host material may be respectively doped at a different predetermined concentration of laser ions. A heat exchanger may be provided to dissipate heat from the first portion and the second portion.

A laser system, comprising:
- a laser disk, comprising:
- a front surface;
- a back surface opposite to the front surface;
- a first portion of laser host material adapted for amplification of laser radiation;
- and
- a second portion of laser host material completely surrounding the first portion of laser host material between the front surface and the back surface and adapted for suppression of ASE, wherein the first portion of laser host material and the second portion of laser host material are both doped with laser ions, each at a different predetermined concentration of laser ions;
- and
- a heat exchanger thermally coupled to the back face of the laser disk to dissipate heat from the first portion and the second portion.

A thin disk laser, comprising:
- a front face;
- a back face parallel to the front face;
- a central portion of laser host material doped with laser ions at a first predetermined concentration for amplification of laser radiation;
- and
- an edge portion of laser host material completely surrounding the central portion between the front face and the back face and doped with laser ions at a second predetermined concentration for suppression of ASE, wherein the second predetermined concentration is substantially higher than the first predetermined concentration.
