Femtosecond lasers spread out new road in fabrics processing because of its specific beneficial properties of ultrashort pulse width and very excessive height depth. the most very important good points of femtosecond laser processing is that powerful absorption may be prompted even through fabrics that are obvious to the femtosecond laser beam as a result of nonlinear multiphoton absorption. The multiphoton absorption permits us to accomplish not just floor but additionally three-dimensionally inner microfabrication of obvious fabrics resembling glass. This power makes it attainable to without delay fabricate third-dimensional microfluidics, micromechanics, microelectronics and microoptics embedded within the glass. extra, those microcomponents might be simply built-in in one glass microchip through the straightforward technique utilizing the femtosecond laser. hence, the femtosecond laser processing presents a few merits over traditional tools corresponding to conventional semiconductor processing or smooth lithography for fabrication of microfluidic, optofludic and lab-on-a-chip units and thereby many researches in this subject are presently being performed. This publication offers a accomplished evaluation at the state-of-the-art and destiny customers of femtosecond laser processing for fabrication of microfluidics and optofludics together with precept of femtosecond laser processing, designated fabrication tactics of every microcomponent and functional purposes to biochemical analysis.
