  • Publication number: 20250147382
    Abstract: A laser system according to an example of the present disclosure comprises: a supercontinuum laser that generates light with a visible wavelength; a wavelength selector comprising a filter whose angle is adjustable and configured to filter the wavelength of light incident from the supercontinuum laser to have a wavelength corresponding to the angle of the filter based on the angle of the filter; a compressor configured to compress the pulse width of light incident from the wavelength selector; and, a non-linear crystal configured to convert the wavelength of light incident from the compressor into an ultraviolet wavelength.
