<p>The present invention pertains to a laser device equipped with a structure for facilitating modifications to the transmission wavelength band of a band pass filter to correspond to the central wavelength of pulse light. In the laser device, if the pulse width of pulse light outputted from a seed light source has been modified, the transmission wavelength of light that passes through a band pass filter is modified according to the central wavelength of pulse light.</p> |
