Abstract
According to exemplary practice of the present invention, a probe laser beam is aligned with a position detector and is spatially/geometrically related to a pump laser beam. A temperature gradient is produced in a medium by the pump beam. Since an increase or decrease in the temperature of the medium is related to an increase or decrease in the refractive index of the medium, position sensing of the deflection of the probe beam relative to the pump beam indicates whether the medium is heating or cooling.
