Broad Area Laser Diode
Product Family
Specification Sheet
The M8xx series of Broad Area Laser Diodes from Axcel Photonics offer
high CW optical power from a 100 micron multi-mode aperture and high
brightness with industry leading reliability. This series of devices is
produced with Axcels advanced wafer growth and facet passivation
technology, which enables inceased performance in all areas including
lower threshold current, increased efficiency, and lower operating voltage.
The M8XX series consists of multi-mode operating lasers with standard
apertures of 50, 100 and 200 microns. Custom devices with non-standard
apertures and wavelengths, including multiple active areas are available.
808 and 830 nm high power Broad Area Laser Diodes are suited to a number
applications including DPSSL pumping, fiber lasers, and materials
processing. Our proprietary epitaxial wafer design and facet passivation
processes significantly increase output power in these broad area devices.
Higher brightness for a given active region, up to 3 Watts for a 100 micron
aperture, is achieved with this revolutionary technology.
Facet Technology
The Axcel facet design, based on Axcels highly reliable telecom design,
increases the COD threshold to 20 MW/cm
2
(several times the industry
standard). This allows the device to operate at higher output powers and
maintain the reliability of the facet structure. The uniformity of the
passivation also contributes to increased reliabilty at these elevated
powers. Controlling the thickness of the passivation material creates
uniform power density across the facet and prevents hotpsots in the facet
structure.
Chip and Sub-mount Options
Axcels products are available as discrete single chips or in Chip On Sub-
mount configurations. Axcel offers B and C-Mount options, all of which
include an isolated fly lead connection for the laser cathode. All multi mode
lasers regardless of sub-mount options are mounted P side down.
Fiber pigtailed lasers are offered on a custom basis only. Please contact your
local distributor or sales office for details.
