MgO:PPLN Crystal Series
A mGreen Module is a single integrated component for green light generation. By pumping the mGreen with an 808nm laser diode, the user can obtain the green light output. A mGreen module consists of 4 elements including a silicon subcarrier; a Nd:YVO4 or Nd: YAG crystal as laser gain media, a MgO:PPLN crystal, and a brass cover.
Shalom EO offers off-the-shelf and custom mGreen modules. The MgO:PPLN crystals incorporated inside the green are used as the frequency conversion element, which converts the 1064nm Nd:YAG laser pumped using an 808nm LD to 532nm green output through SHG. Besides, 561nm laser output can be obtained from SHG of 1122nm Nd:YVO4 laser. The PPLN crystal and the Nd:YAG/Nd:YVO4 crystal are assembled with a copper heat sink. Our mGreen modules feature compact dimensional design, high output power, high conversion efficiencies, and allow convenient integration. With the combination of excellence, Shalom EO’s mGreen modules serve as indispensable components for your laser systems.
