KTP532/YAG laser and its application to processing amorphous siliconsolar cells,

摘要

Abstract: The purpose of program is researching the green laser amorphous silicon (a-si) solar cells material processing system and the technology of processing. The a-si cells absorption spectrum peak due to light wavelength is near 0.55 $mu@m region, which is very closed to 0.53 $mu@m wavelength, the second harmonic generation of 1.06 $mu@m Nd:YAG laser. Using nonlinear crystal frequency doubled and Q-switch modulating technology, we can obtain more than 10 W 0.53 $mu@m laser power.!3
