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.
