The QD-Cx840-S & QD-Cx840-H products are based upon highly performing 40W 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 (FAC lens, Antireflection coated) can also be assembled to reduce the divergence below 1 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…
