Overview

The 1500 to 1600 nm auraTM diode laser offers extraordinarily high-power output in a nearly diffraction-limited single spatial mode. The device architecture is based on a single-mode tapered waveguide laser structure. Built-in wavelength stabilization is not included. The nearly diffraction-limited output enables efficient coupling to single-mode fiber and maximizes far-field irradiance when collimated in free space. Various packaging configurations are offered including: 1) hard-soldered junction-down on C-mount, 2) hard-soldered junction-down on ceramic submount, and 3) unsoldered bare chip.

The auraTM product line is intended to address applications such as free space optical communication, sensing, and LIDAR in consumer, industrial, and defense markets by enabling watt-level direct use output from a semiconductor chip source.
