Emission spectra of zircaloy-4 sample containing 800 mg/kg of H. (A) Only the first laser was turned on with the same energy of 82 mJ in He gas at 3 kPa. The gate delay and gate width of the detection system were set as 200 ns and 50 μs, respectively, after the initiation of the first laser. (B) Both lasers were turned on as per the conditions mentioned in Fig. 4. The Echelle spectrograph of Andor M500 was used to obtain the wide wavelength range. The Al sub-target was used in this experiment.
