ABSTRACT:
A conductively cooled, optically diode-pumped slab laser comprises a slab laser host 1 having transparent, thermally conductive heat sink means 2 bonded to its pump faces. Semiconductor lasers or light emitting diodes 3 are mounted on the heat sink means for generating pumplight which is transmitted through the heat sink means 2 into laser host 1 to cause lasing. Heat flow within the laser host 1 is substantially bi-directional, thereby minimizing optically harmful thermal distortion of the host. The apparatus can function as laser amplifier, laser oscillator or combined oscillator/amplifier.
