Abstract
The shape of combustion nozzles varies from large diameter to small diameter ones. In the case of small nozzle, nozzle exit can be easily winkled or damaged in machining process. Femtosecond laser is a micro machining technology that is able to drill a small nozzle without damaging the nozzle exit. In this experiment, a small nozzle of combustion was fabricated by using a femtosecond laser. The fabricated nozzle of combustion provided a very small nozzle diameter with clean nozzle exit without wrinkling or collateral damage.
