System capabilities were demonstrated by inscribing Fiber Bragg Gratings and waveguides using a 1040 nm laser, extended to 750 nm and 1260 nm with an Optical Parametric Amplifier. Precise control over FBG pitch and length were achieved, with results showcasing strong refractive index modifications. FBGs exhibited reflectivity’s exceeding 25 dB, and bandwidth of less than 200~pm for 1~mm long second order devices. High temperature annealing to 1000~$^{\\circ}$C was performed and a combination of Type 1 and Type 2 index change is observed. Further investigations included inscribing waveguides and exploring the impact of different laser wavelengths on FBG inscription performance. Design challenges and solutions associated with the micromachining platform, including system integration and tuning, are discussed. Experimental results highlight the effectiveness of the system to produce quality FBGs and waveguides, demonstrating flexibility for high precision laser material processing.","abstract_html":"This thesis presents the development of a multi-axis femtosecond laser micromachining platform.
