A mount for suspending a laser medium has a cross section profile. The mount is configured to conduct heat away from the laser medium without imparting undue stress. The mount includes a laser host medium having a first cross section profile. A heat sink defines a bore. The bore has a second cross section profile configured to envelop the first cross section profile and further defines a generally uniform interspace between the first cross section profile and second first cross section profile. An amalgam of a mercury soluble metal is formed to substantially fill the interspace to support the laser host medium.
