1. A laser system for amplifying laser light generated from a laser light source and emitting the laser light, the laser system comprising:
an optical element that is provided in an optical path of the laser light and transmits the laser light;
controlling circuitry to control power to be supplied to the laser system;
an imager to capture an image of the optical element; and
an image processing circuitry to process the image of the optical element captured by the imager, wherein
the image processing circuitry comprises reference image selecting circuitry in which reference images of the optical element corresponding to power information relating to the power are prepared in advance and one of the reference images corresponding to the power information is selected, and comparing circuitry to compare a captured image of the optical element captured by the imager with the reference image selected by the reference image selecting circuitry, the reference image corresponding to the power information at a time of image capturing by the imager.
