ISO/TS 17915:2013 describes methods of measuring temperature, injected current dependence and lasing spectral line width in relation to semiconductor lasers for sensing applications. ISO/TS 17915:2013 is applicable to all kinds of semiconductor lasers, such as edge-emitting type and vertical cavity surface emitting type lasers, bulk-type and (strained) quantum well lasers, and quantum cascade lasers, used for optical sensing in e.g. industrial, medical and agricultural fields. ISO/TS 17915:2013 is an application of ISO 13695, in which the physical bases are explained.
