Abstract
Detection of infrared radiation (10 mu m) by a nonlinear up-conversion technique under a tangential phase-matched situation in AgGaS2 crystal with Nd:YAG laser as a pump has been demonstrated. A wide angular tolerance has also been obtained with a view to achieving mechanical stability. Its capability of detecting a low-level infrared signal at room temperature and its temperature-dependency have also been demonstrated.Keywords
