Abstract
An evaluation method evaluates characteristics of laser light in an optical apparatus. The optical apparatus includes a laser light source that emits laser light, a detector that detects laser light, and an optical shutter that switches between irradiation of the detector with laser light and cut-off of laser light to the detector. The evaluation method includes transmitting to the optical shutter, an instruction to switch between irradiation and cut-off, obtaining temporal change in quantity of light detected by the detector during a period from transmission of the instruction until completion of switching, and evaluating characteristics of laser light based on the obtained temporal change.
