| 简介 |
PURPOSE : A continuous wave supercontinuum laser source resonator, and a medical diagnostic device are provided to prevent tissues from being damaged due to instantaneous over-output of a pulse mode supercontinuum laser source by using a continuous output waveform in the medical diagnostic device.
CONSTITUTION : A continuous wave supercontinuum laser source resonator includes a pumping light coupler, a rare-earth element addition optical fiber(10), and a high nonlinear optical fiber(20). The pumping light coupler inputs pumping light into the resonator. The rare-earth element addition optical fiber(10) receives the pumping light and converts the pumping light into a seed light of a predetermined wavelength band. The high nonlinear optical fiber(20) converts the light, which is converted by the rare-earth element optical fiber(20) and oscillated in the resonator, into a continuous wave supercontinuum laser source. The laser source resonator is a Fabry-Perot type resonator further having a mirror connected to the pumping light coupler.
