- This is the first example of a highly compact graphene-coated thin film pulsed waveguide laser grown via a laser deposition technique (PLD). This work was performed within an EPSRC grant, EP/L021390/1, ‘lasers making lasers’ £365K, under the ‘manufacturing with light’ call, which then led to a larger EPSRC follow-up grant EP/N018281/1, at £876K. These finger-nail-size laser systems are highly efficient (70% optical-to-optical conversion) and are applicable for applications in marking, medicine, manufacturing and sensing. Further follow-up funding has recently been won from NASA for satellite-based systems for greenhouse gas sensing establishing the unique merits of these PLD-grown lasing waveguides.
