Optically Stimulated Luminescence (OSL) based radiation monitoring is now a widely accepted technique to measure the radiation dose absorbed by material for applications in personal, environmental, medical and retrospective dosimetry. In this regard, OSL readers are greatly needed in research and academic institutions for the development and characterization of OSL phosphors. In general, most OSL readers are designed for applications in dating archaeological and geological samples. These readers available in the market are very costly and not easy to use for researchers. Therefore, for laboratory applications and experiments, simple OSL readers need to be developed for the research of OSL-sensitive phosphors for their applications in routine personal, environmental radiation monitoring, and medical dosimetry. The OSL reader systems need to be highly sensitive and compact for infield measurements. Developing detectors with higher sensitivity can improve the detection of low-intensity luminescence signals, making it easier to measure lower doses accurately. In conventional OSL reader, LED is generally the obvious choice as a light source for optical stimulation due to its cost effectiveness and ease of access. However, in the recent past efforts have been made to use Laser as a light source to explore the advantage of their narrow bandwidth. On similar lines, a laser based OSL reader has been developed and thoroughly characterized using OSL discs.
