ABSTRACT:
Apparatus and method for estimating a downhole fluid property using a carrier conveyable into a well borehole, one or more light sources carried by the carrier, the one or more light sources comprising at least one quantum cascade laser light source, a fluid sample cell that receives light emitted from the one or more light sources, and at least one photodetector that detects light emitted from the one or more light sources after the light interacts with a fluid in the fluid sample cell.
