Since the discovery that tightly focused femtosecond laser pulses can induce a highly localised and permanent refractive index modification in a large number of transparent dielectrics. the technique of ultrafast laser inscription has received great attention from a wide range of applications. In particular. the capability to create three-dimensional optical waveguide circuits has ope... https://parisnaturalfoodes.shop/product-category/body-wash-coconut/
