Abstract
A bypass apparatus is attachable to and detachable from a laser apparatus, and constitutes a bypass optical path bypassing a pulse width stretching apparatus stretching the pulse width of pulse laser light having entered the pulse width stretching apparatus, the bypass apparatus including optical elements constituting the bypass optical path, and an enclosure housing the optical elements, the optical elements including a first highly reflective mirror that reflects the pulse laser light entering the pulse width stretching apparatus out of the pulse width stretching apparatus and that guides the reflected pulse laser light to the bypass optical path, and a second highly reflective mirror reflecting the pulse laser light reflected off the first highly reflective mirror and incident on the second highly reflective mirror through the bypass optical path to cause the reflected pulse laser light to return to a light-exiting-side optical path of the pulse width stretching apparatus.
