Features
Uncollimated (MN-series) or fast-axis
collimated radiation (MY-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
m) 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".
