In this paper, we report the development results for a femtosecond (fs) laser machining system and a gas cell for laser wakefield acceleration research. The developed fs laser machining system consists of a mode-locked Ti:sapphire oscillator, a Ti:sapphire regenerative amplifier, a three-dimensional-moving stage, etc. The system is used to micro-machine a special-type gas cell, that will be used as a plasma source in laser-plasma acceleration research. The gas cell was designed following computational-fluid-dynamics (CFD) simulations, and the internal gas distribution in the gas cell was measured by using a Mach-Zehnder interferometer. In this paper, some of the development and research results for the laser micro-machining system and the gas cell are reported.
