Abstract
A laser device includes: a light source that emits infrared light by switching the infrared light between pulsed light, at least a part of the pulsed light has an intensity greater than or equal to a first threshold value, and continuous light with an intensity less than the first threshold value; and a wavelength converter that receives the infrared light and wavelength-converts the infrared light with an intensity greater than or equal to the first threshold value into visible light.
