Product Overview:

These high power laser diodes offer up to 85 Watts of CW optical output power into a 105 micrometer fiber pigtail. These devices are based on a high reliability multi-single emitter design. Their multi-single emitter based design delivers optimal uniform heat dissipation through the package which leads to excellent thermal performance and 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 0.14 NA. They ship with 2 meter unterminated fiber pigtail. The 85W-976NM model is used extensively in materials excitation, materials processing and in fiber laser pumping applications. They typically ship on a 5 to 7 day lead time. Proper attention should be paid to heat sinking and thermal control of these high power sources. Compatible actively cooled heat sinks can be found on LaserDiodeControl.com.
