Abstract
A laser device capable of efficiently oscillating laser light and always obtaining a stable beam form is provided. For this purpose, in the laser device including an amplifying section () in which a laser medium is amplified to oscillate laser light (), and an optical element for separating part of the laser light () oscillated, and shaping a beam form of the laser light () into a desired form to output the same, wherein the optical element has at least either one of a partial reflecting portion () for partially reflecting the laser light () or a non-reflective portion () for transmitting the laser light () at high transmissivity, each of which is provided on approximately a center portion, and a total reflecting portion () which is provided outside a perimeter of the partial reflecting portion () or the non-reflective portion (), and which reflects the laser light () at high reflectivity.
