| Summary: | 碩士 === 國立中央大學 === 光電科學與工程學系 === 104 === Solid-state dual-wavelength lasers were constructed using a Nd:GdVO4 as the gain medium. The output couplers used in these laser cavities were temperature controlled volume Bragg gratings. The gain of the laser cavities was adjusted by changing the temperatures of the VBGs. Temperature adjustment mainly results in thermal expansion of the VBGs, and shifts the corresponding diffraction spectrums, which will then alter the corresponding emission cross section of the laser outputs. Through this method, three dual-wavelength lasers utilizing different emission peaks of the Nd:GdVO4 were realized. The third wavelength was achieved through an additional Nd:YAG and VBG inside the laser cavity.
