Passively Cooled Diode Laser Bar Both Axes Collimated 25 ... 30 W cw SPL MBxx Preliminary Data Features Applications * Collimated radiation source for cw operation in a sealed housing * Very low fast and slow axes divergence angle * No water required, passive cooling through copper mount * High reliable strained layer InGa(Al)As/GaAs material * Standard wavelength selection is 3 nm, others on request * Low smile, low mechanical tolerances * * * * End pumping of rods and fibers Soldering, direct material processing Marking, surface processing Medical 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".
