cooled 50W 60W CW Diode Bars
QD-C1950-H or QD-C1960-H
DESCRIPTION
The QD-C1950-H and QD-C1560-H products are based upon highly performing 50W and 60W CW Laser
Diode Bar Arrays. The Laser Diode structure is multiple emitters spaced on a monolithic 1cm "bar". The bar is
mounted with the active zone (P side) towards a conductively cooled submount with low thermal resistance.
The quality quantum well structure and of the process leads to high electrical to optical conversion efficiency
and reliability.
The compact and rugged package allows easy connection to an efficient heat exchanger. So the submount
temperature can be adjusted to tune the emission wavelength. With this open package the optical beam can
be directly used to achieve efficient coupling.
A fast-axis collimation lens (Antireflection coated) can also be assembled to reduce the divergence to 0,5 deg.
This linear bar array is ideal for applications which request high output power like pumping solid state lasers,
illuminators, medical therapy, graphic arts, material processing...
