Product Overview:

These high power laser diodes offer up to 320 Watts of CW optical output power at a center wavelength of 976 nm (+/-3 nm). They are also available at 915 nm. They have 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 and a long lifetime. Several key features include 1040 nm to 1200 nm 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 0.18 NA. The module has a 2 meter unterminated fiber pigtail. Polished connector options are available on request.
