Abstract
The present application discloses an improved thermopile laser sensor apparatus and methods of use. In one embodiment, the apparatus includes a sensor body having a first sensor body recess and a second sensor body recess formed therein, with a substrate positioned in the first sensor body recess in thermal communication with the sensor body. The substrate includes at least one absorber attached thereto and configured to absorb a portion of a beam of laser energy. A first thermal sensor in thermal communication with the substrate and the sensor body may be formed on or attached to the substrate. A second thermal sensor in thermal communication with the sensor body may be positioned in the second sensor body recess. A thermal barrier configured to reduce the rate of transfer of thermal energy from the substrate to the second thermal sensor may be positioned between the substrate and the second thermal sensor.
