<p>The present invention relates to a laser output device that outputs high-repetition-rate pulse laser light having a narrow pulse width. The device according to the present invention comprises: a pulse driving driver that generates a driving signal; a laser diode that is driven by the driving signal of the pulse driving driver to oscillate the pulse laser light; and an amplifier that amplifies the pulse laser light oscillated by the laser diode. The amplifier comprises: a first pumping light source that supplies first pumping light; a wavelength division multiplexer that combines the pulse laser light with the first pumping light and outputs the result; and a first amplifier that comprises a first optical fiber which amplifies the light output through the wavelength division multiplexer to a single mode.</p> |
