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 diffractionlimited
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 hermeticallysealed
package with collimated and fiber-coupled output, and bare die/bars.
