Abstract:
1. A laser module being operative to extract energy from a laser disk by achieving multiple passing through the disk, the laser module comprising: a disk comprised of lasing material having opposing first and second surfaces and a gain region comprised of excited lasing material, the disk being rotatable about a rotation axis; a rotation mechanism in mechanical communication with the disk for rotating the disk; a laser beam passing through the gain region by entering through the first surface and exiting through the second surface; a heat sink disposed substantially adjacent at least a portion of the disk such that as the disk rotates, heat from different portions of the disk dissipates as each portion comes into thermal communication with the heat sink; first and second mirrors positioned along the laser axis adjacent the second surface, wherein the first mirror is oriented to receive the laser from the laser source and reflect the laser toward the second mirror, and wherein the second mirror is oriented to receive the laser from the first mirror and reflect the laser through the gain region; third mirror positioned along the laser axis, the third mirror being oriented to receive the laser beam from the second mirror and reflect the laser beam through the gain region.
