Overview

The 870 to 1000 nm single spatial mode diode laser offers unprecedented power output in a nearly diffraction-limited mode. The device architecture is a single-mode ridge waveguide Fabry-Perot laser structure.  This laser is ideally suited for applications including resonant end-pumping of Nd and Yb-doped solid state and fiber lasers with low quantum defect..  The nearly diffraction-limited output enables precise matching of the pumped gain region with the solid-state laser cavity mode and efficient coupling to single-mode fiber.

The packaging format is as follows: the device is hard-soldered junction-side down onto a C-mount package. The C-mount has a copper base with a CuW expansion-matched insert.  Other heatsink formats are available including conductive submounts, ceramic submounts, 14-pin butterfly hermetically-sealed package with collimated and fiber-coupled output, and bare die/bars.
