Product Overview:

These high power laser diodes offer up to 540 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. Several key features include 1040nm to 1200nm feedback protection with feedback isolation > 30 dB across the range. Advanced processes for coupling efficiency allows these modules to deliver up to 95% of their output power within 0.17 NA. They ship with 2 meter (typ) unterminated fiber pigtail.
