These high power fiber coupled laser diodes offer up to 300 Watts of CW optical output power into a 200 micrometer fiber pigtail. These devices are based on a high reliability multi-single emitter design. Their multi-single emitter based design delivers very good heat dissipation through the package which leads to excellent thermal performance over a long lifetime. Advanced processes for coupling efficiency allows these modules to deliver up to 95% of their output power within 0.17 NA. They ship with 1.5 meter (typ) unterminated fiber pigtail. A Peliter and Fan cooled customized heat sink is avalable for this laser. Also, pre-configured current source and temperature controller modules are available to connect to the heat sink unit.
