The new FERT-525-XW-FC105 is a series of fiber-coupled laser diodes at 525nm with output powers between 1W to 4W. The output fiber is a 105µm detachable multimode fiber with either FC or SMA connector. By connecting a beam homogenizer the laser provides a perfect flat-top beam profile with excellent spatial mode. The operating temperature range is very wide and covers a range from -40°C to +55°C. With dimensions of just 34mm x 20mm x 15mm (LxWxH) at 1W to 72mm x 44mm x 21mm (LxWxH) at 4W they are very compact. These features and the high reliability make them the optimal laser source for applications like target designation or remote source lighting.
