To be able to drive the micro unmanned aerial vehicle(UAV) with the theory of laser ablation, the quantum cascade laser ( QCL) driver is designed, which consists of a voltage generator module, the inner-feedback constant current source module, the external feedback module and the protection circuit. The QCL driver can generate high precision current with the linearity 99. 93% of voltage. The driving test on a QCL with centre wavenumber 2083 cm-1 is performed using the proposed driver, and the output power of QCL can goes up to 130 mW. The result show that the QCL driver can be utilized in micro UAV.
