Abstract

PURPOSE:To make the spatial strength distribution uniform by a method wherein a medium crystal having an activated ion concentration distribution which is related in opposition to the spatial strength distribution of the output mode of an oscillator is provided in an amplifier and beams from the oscillator are made to pass through the crystal on the occasion when the laser device is composed of the combination of the oscillator and amplifier. CONSTITUTION:The laser device is constituted by the combination of the oscillator and amplifier and the oscillator is provided with an Xe flash lamp 6 for excitation and a rod 7 such as Nd-YAG, while one end surface of the rod 7 is fitted with a reflecting mirror 8 and the other end surface thereof with an output mirror 9. Next, the amplifier is arranged in opposition to the output beams from the output mirror 9, while it is also provided with an Xe flash lamp 6 and further with the medium crystal for amplification, and through this crystal 11 the output beams are emitted. In this constitution, the activated ion concentration distribution of the crystal 11 is selected to be in the opposite relation to the spatial strength distribution of the output mode of the oscillator, and thus the beams 12 are made to be amplified uniformly in the spatial relation.
