碩士 === 國立交通大學 === 理學院應用科技學程 === 104 === We demonstrate a compact efficient high-power collinear dual-wavelength solid-state laser by Nd:YVO4/Nd:GdVO4 and Nd:GdVO4/Nd:YVO4 crystal. The study is based on using 808 nm LD semiconductor laser diode) to pump to two neodymium-doped diffusion-bonded crystals respectively. We obtain a tunable output power by controlling the laser waist position on gain medium at both continuous wave and passive quality system. It is worth mentioning that performance of dual-wavelength solid-state laser is highly dependent with laser pulse repetition rate. We are looking forward to providing a new technique to achieve dual-wavelength laser for application of military, medical, aviation, industrial, science, etc.
