Passively Cooled Diode Laser Bar
SPL MNxx
Only available in North America
SP-pack. (left), DL-pack. (right)
Features
• Uncollimated (MN-series)
• 1 cm-laser bar mounted on passive heat sink,
no water required
• Highly reliable strained layer InGa(Al)As/GaAs
material
• Standard wavelength selection is
±
3 nm, others
on request
• Low smile (< 1
µm)
and low mechanical
tolerances
Applications
• Pumping of solid state lasers (Nd: YAG,
Yb: YAG, …)
• Direct industrial applications (soldering, surface
treatment, marking, …)
• Heating, illumination
• Medical and printing applications
Safety Advices
Depending on the mode of operation, these
devices emit highly concentrated non visible
infrared light which can be hazardous to the
human eye. Products which incorporate these
devices have to follow the safety precautions
given in IEC 60825-1 “Safety of laser products”.

Lowering the diode laser temperature below 15°C is only suitable in a closed housing with dry inert atmosphere (e.g.) nitrogen.
Condensation of water or other liquids irreversibly damages the diode lasers and must be avoided
.
Storage and shipping of diode lasers must be done with shortened electrical contacts and in a clean and dry atmosphere in a
temperature range of 0°C up to 60°C.
