Product Overview:

976nm Single-Emitter 140 Watt Multimode Laser Diode

These high power pump lasers deliver very stable wavelength light with a narrow emission bandwidth due to the integrated volume Bragg grating. They deliver up to 140 Watts in CW mode via the 105µm-core fiber. Pulsed-mode operation is also possible.

The laser module is designed to be heat-efficient, but the package must be securely mounted to a temperature-controlled mounting surface to ensure safe operation and long operating lifetimes. Contact us for recommendations, or consider the CW source system that integrates this laser with the driver electronics, temperature controller, and heat-sink. See below for details.
