Canadian laser developer C2C Link has introduced a smaller version of their mGreen laser diode module. The new diode-pumped solid-state laser (DPSS) uses 1% doped neodymium:yttrium orthovanadate (Nd:YVO4) and 5mol% magnesium oxide periodically poled lithium niobate (MgO:PPLN) crystals to produce 532nm laser light. Mounted on a silicon substrate, the crystals are precisely aligned with an air gap. The 1W green laser is said to offer a wall-plug efficiency that exceeds 15% in a package less than 6mm thick. The green miniLaser is currently shipping to C2C customers. Pricing was not disclosed.
PMA Research’s projector market research has followed the development of the green lasers needed by MEMS and MOEMS imagers. While several companies are developing (and shipping) direct diode green lasers, C2C is one of a very few producing synthetic (DPSS) modules.
