Notes:
By focusing femtosecond laser pulses in the bulk of a quartz wafer, sub-surfacewaveguides were microexploded. The material around the femtosecond laser inducedmicroexplosive zone was densified, which altered local refractive index. Changes in materialdensity can take corresponding variations in nanomechanical properties, which were proved by thedepth dependent modulus and hardness variations tested by nanoindentation in the area around themicroexplosive zone. Changes in refractive index were correlated with residual strains along radialdirection of the waveguide cross section. An equation of residual strain in such area that based onnanoindentation data was set up, so as to discover density and refractive index variations in theadjacent areas of femtosecond laser microexplosive zone indirectly
