  • Nanosecond pulse laser device and alternate laser wavelength output method thereof
    Patent number: 9667027
    Abstract: The present invention relates to a nanosecond pulse laser device. The nanosecond pulse laser device of the present invention comprises: a light source which outputs a nanosecond pulse laser beam; a lens which focuses the laser beam; a Raman shift optical fiber which generates pulse lasers corresponding to a plurality of wavelengths through stimulated Raman scattering of the focused laser beam; a wavelength divider which divides, from among the pulse lasers, the pulse lasers of a predetermined wavelength; an optical switch which selects the pulse lasers outputted from the wavelength divider to mutually alternate the wavelengths in response to a switch control signal which is applied from the outside; and a wavelength combiner which combines and outputs the pulse lasers whose wavelengths are alternatively outputted from the switch.
    Type: Grant
