We present a novel nonlinear imaging method that utilizes femtosecond laser-induced plasma emission to probe microscopic structures embedded inside transparent materials. This nonlinear diagnostic tool can resolve either elemental or structural variations of the sample of interest and provide significant improvements over the ordinary linear microscopes by having much higher contrast ratios for the observed areas of different refractive indices. Examples of using this technique to examine the microstructures fabricated by ultrashort laser pulses inside optical glass are presented.

  11. Note that, as a result of the low scanning speed (0.2 mm/s) and long integration time (0.5 s/pixel) of the lock-in amplifier, it takes about 4 h to obtain a picture of 25,600 pixels like the one shown in Fig. with our current experimental setup. It is, however, expected that this image acquisition time can be reduced dramatically to less than 1 min when a high-speed laser scanner and a high repetition rate femtosecond oscillator are employed.
