The spread of laser equipments in the transportation and medical industries is recording a constant increase. A key aspect in utilizing laser technology is calibration and ensuring that the devices always function at their optimum parameters. The only convenient method to reliably determine the status of the device is to analyse the properties of the emitted radiation. Thus, the project proposes an innovative concept for a laser energy/power meter.
At the core of the project there will be detailed investigations of pyroelectric materials and of the principles of calorimetric measurements. Such films and elements will be deposited and prepared by the partners from INCDFM. The coordinating team from Apel Laser will provide the mechanical, electronic and data transfer integration elements of the device, necessary for satisfying the future commercial requirements.
This collaboration aims to innovate some key aspects of laser radiation sensors, such as metallic surface layers for enhancing the induced electrical signal, utilizing different combinations of polymeric, dielectric and composite metamaterials to ensure a wide absorption spectrum. It is also desired to implement a ‘light-trap’ geometry to facilitate multiple absorptions and increase the thermal variation within the device and improve the detection limit.
At the end of the preliminary tests the processes necessary for implementation will be optimised.
