Abstract
Optical coherence microscopy (OCM) is used to image femtosecond laser direct written buried structures created within transparent media. Volumetric structures of optical damage and laser-induced refractive index change were produced in fused silica and borosilicate glass, respectively. Noninvasive 3D imaging of the structures was successfully demonstrated by a custom built OCM. High signal to noise ratio was obtained since the optical glasses have high transparency at the probe wavelength centered at 800 nm.
