摘要：
A green laser with multi-wavelength emission was demonstrated using intracavity frequency conversion (frequency doubling and frequency summing) in a Nd:Mg:LiTaO3 laser. MgO-doped periodically poled lithium niobate (MgO:PPLN) was used as a nonlinear crystal in this work. A 62 mW that could emit light at 546, 542 and 538 nm was obtained by end pumping with a 808-nm laser diode. The speckle contrast ratio for the three-wavelength laser was only 3.36 %, a quarter of the value of the conventional 532-nm laser.
