A control section as a tissue identification device includes: an absorbance ratio calculating section configured to calculate the ratio of an absorbance indicated by a transmitted portion of first inspection light transmitted through biological tissue to an absorbance indicated by a transmitted portion of second inspection light transmitted through the biological tissue; and an identification information generating section configured to generate identification information indicative of the type or state of the biological tissue by determining within which of a plurality of preset numerical ranges the ratio falls.

Tissue identification device, tissue identification system, method of identifying tissue, and storage medium

Provided is a laser device in which: a laser medium doped with ytterbium emits light upon absorption of excitation light; the light emitted by the laser medium is amplified to obtain output light; and the output light is outputted in the form of a plurality of pulses. In the laser device, a spatial filter is disposed in the optical path of the light emitted by the laser medium or is disposed in the optical path of the output light outputted from an optical resonator, the spatial filter being configured to filter out a portion of the light or of the output light around the optical axis.
